Answer 1

200

Explanation:

Change 8 hours to minutes so the units are the same. 8(60) = 480. Using a proportion the equation is 5/12 = j/480. [jumps/minutes] To solve the equation, cross multiply: 12j = 5(480) ; 12j = 2400; j = 2400/12; j = 200.

Answer 2

The answer is 200 !
Explanation - if she jumped 5 times in 12 minutes,there are 60 minutes in a hr ! So 60 divided by 12 is 5 ! So next multiply 5 times 5 to get 25 . So meaning she jumped 25 times in a hr ! Then multiply 25 times 8 to get 200
