How many seconds are in an hour?

There are really only 23hrs and 56 mins in a day

How do you convert from minutes and seconds to months and vice versa? What about to years?

Just convert the units! For instance: 1000 min x (1 hr / 60 min) x (1 day / 24 hr) x (1 month / 30.5 days) = 1000 / (60 x 24 x 30.5) months = 0.02277 months So 1000 minutes = 0.02277 months Also: 1 month x (30.5 days / 1 month) x (24 hr / 1 day) x (60 min / 1 hr) x (60 sec / 1 min) = (1 x 30.5 x 24 x 60 x 60) sec = 2,635,200 sec So 1 month = 2,635,200 seconds And: 0.02277 months x (1 year / 12 months) = 0.001898 years So 1000 minutes = 0.001898 years

why would it be seconds = 1/60 of a minute. It would be easier to say minute = 60 seconds?

It might have wanted to express minute = 60 seconds with fractions.

for the first section and the third question it says what the average time to pick up the phone is seconds but what if you can't find your phone.Then it can take more than a few seconds. It could take roughly 15 seconds

I lost my phone so it toke longer to find. (more like 1 hour)

Review the size of seconds, minutes, and hours and how to convert between them. Then, try some practice problems.

Units of time

Units of time measure how long something lasts. For example, how many seconds can you hold your breath, or how many minutes long is your favorite movie?

How long are different units?

A second is a short amount of time. It takes about 1 second to turn on a light or open the refrigerator door.

A minute is equal to 60 seconds. It takes about 1 minute to brush your teeth.

An hour is equal to 60 minutes. Extracurricular activities (gymnastics, piano lessons, soccer practice) often last about 1 hour.

Converting larger units to smaller units

1, start text, space, m, i, n, u, t, e, end text, equals, start color #1fab54, 60, end color #1fab54, start text, space, s, e, c, o, n, d, s, end text
1, start text, space, h, o, u, r, end text, equals, start color #1fab54, 60, end color #1fab54, start text, space, m, i, n, u, t, e, s, end text

To convert larger units to smaller units we multiply the number of larger units by start color #1fab54, 60, end color #1fab54.

Example: Converting hours to minutes

1, start text, space, h, o, u, r, end text, equals, start color #1fab54, 60, end color #1fab54, start text, space, m, i, n, u, t, e, s, end text
start color #11accd, 6, end color #11accd, start text, space, h, o, u, r, s, end text, equals, start color #11accd, 6, end color #11accd, times, start color #1fab54, 60, end color #1fab54, equals, 360, start text, space, m, i, n, u, t, e, s, end text

Converting smaller units to larger units

To convert smaller units to larger units we divide the number of smaller units by start color #1fab54, 60, end color #1fab54.

1, start text, space, s, e, c, o, n, d, end text, equals, start fraction, 1, divided by, start color #28ae7b, 60, end color #28ae7b, end fraction, start text, space, m, i, n, u, t, e, end text

1, start text, space, m, i, n, u, t, e, end text, equals, start fraction, 1, divided by, start color #28ae7b, 60, end color #28ae7b, end fraction, start text, space, h, o, u, r, end text

Example: Converting seconds to minutes

1, start text, space, s, e, c, o, n, d, end text, equals, start fraction, 1, divided by, start color #28ae7b, 60, end color #28ae7b, end fraction, start text, space, m, i, n, u, t, e, end text

start color #ff00af, 30, end color #ff00af, start text, space, s, e, c, o, n, d, s, end text, equals, start fraction, start color #ff00af, 30, end color #ff00af, divided by, start color #28ae7b, 60, end color #28ae7b, end fraction, equals, start color #6495ed, start fraction, 1, divided by, 2, end fraction, end color #6495ed, start text, space, m, i, n, u, t, e, end text

  Just convert the units!
  
  For instance:
  1000 min x (1 hr / 60 min) x (1 day / 24 hr) x (1 month / 30.5 days)
  = 1000 / (60 x 24 x 30.5) months
  = 0.02277 months
  
  So 1000 minutes = 0.02277 months
  
  Also:
  1 month x (30.5 days / 1 month) x (24 hr / 1 day) x (60 min / 1 hr) x (60 sec / 1 min)
  = (1 x 30.5 x 24 x 60 x 60) sec
  = 2,635,200 sec
  
  So 1 month = 2,635,200 seconds
  
  And:
  0.02277 months x (1 year / 12 months)
  = 0.001898 years
  
  So 1000 minutes = 0.001898 years

  6 minutes is not enough time for their to be an hour because an hour requires 60 minutes. Therefore if you were do divide 6(minutes) by 60 you would get 0.1, That being the amount of hours in 6 minutes.
