• i do not know
• alright, I got a question:

Lightning McQueen is in a race but his engine is not running consistently.
He covers one half of the total distance of the race in the first hour,
a fifth of the total distance in the next hour,
and one-sixth of the total distance in the third hour.
He is currently 11.2 km from the finish.
What is the total distance (in km) of the race?

How would you make this an equation and find x?

cause i tried looking for an algebra video with something similar but i couldnt find one anyways so...
• On , Khan wrote "yos" instead of "yds"
• Anybody know how 2 get a black hole badge?
• Maggie had walked 9,000 feet then she walked 1,000 more how many YARDS did Maggie walk?
• 9,000+1,000 is 10,000 feet. However, to convert feet to yards you need to divide by 3. So the answer is 10,000/3 or 3333.3333...
• i still dont understand...
• What is
One half-kilogram of bulk sunflower seeds costing 70 cents per 100 grams
• How many grams are in a kilo gram? 1000. It's 70 cents for every 100 grams. There are 10 sets of 100 grams in 1000grams. 100g + 100g+ 100g + 100g + 100g + 100g + 100g+ 100g + 100g + 100g = Total Cost of sunflower seeds. Convert the 100 grams to 70 cents each. You'l get 10 sets of 70 cents. Instead of trying to add all ten up, multiply 10 by 70. Equals 700 cents. Or 7 dollars.
