Question

Jason burned 1400 calories Friday playing one hour of basketball and canoeing for two hours. On Saturday he spent two hours playing basketball and three hours canoeing and burned 2500 calories. How many calories did he burn per hour when playing basketball?

Answer 1

To find out how many calories Jason burned per hour when playing basketball, calculate the total calories burned during basketball and divide it by the total number of hours he played.

Step-by-step explanation:

To find out how many calories Jason burned per hour when playing basketball, we need to calculate the total calories burned during basketball and divide it by the total number of hours he played.

On Friday, he burned 1400 calories playing basketball for 1 hour and canoeing for 2 hours, which makes a total of 1400 - 3 * (1+2) = 1400 - 9 = 1391 calories burned playing basketball.

For Saturday, he burned 2500 calories in total, and since he played basketball for 2 hours, he burned 2500 - 2 * x = 2500 - 2x calories playing basketball.

By solving the equation 1391 = 2500 - 2x, we can find the value of x, which represents the number of calories he burned per hour when playing basketball.
