Question

A runner burned 120 calories on a 1.6

km run. How many calories would
they burn on a 5 km run?
​

Answer 1

375 calories

Explanation:

`(120)/(1.6) = (x)/(5)`

next you would cross multiply

`1.6x = 600`

then you would divide by 1.6 on both sides

`x = 375`

and 375 calories should be ur answe

Answer 2

Answer: 375 calories

Form a proportion. Let x be the number of calories burned on a 5 km run.

`(120)/(1.6) = (x)/(5)`

Solve for x by cross-multiplying.

`1.6x = (120)(5)\\1.6x = 600\\x = 375`
