while riding her bike, jennifer burns 450 calories every 1/2 hour. Based on this rate, how many calories will jennifer burn if she rides her bike for 1 3/4 of an hour?

Answer 1

First, multiply 450 by 2, which is 900 calories for one hour. Now, for the 3/4, set up a proportion.

.50 / 450 = .75 / ?

450 X .75 = 337.5

337.5 / .50 = 675.

So, Jennifer will burn 675 calories every 3/4 of an hour.

900 + 675 = 1575, the number of calories Jennifer will burn if she rides her bike for 1 3/4 hours.

Answer 2

There is a question similar to this on my test.

For mine it's 154 -Ibs and that he burns 420 calories on a bike. And, that you have to write a function and explain stuff.

SO HERES MY ANSWER:

It says he burns 420 calories every hour
