Question

Ji-yoon jumped 150 jumped in 10 hours. At that rate, how many times would she jump in 12 minutes

Can someone please help me my sub teacher doesn't know either

Answer 1

3 jumps in 12 minutes

Explanation:

Lets start by converting the rate of jumps in 10 hours to 1 hour. If we divide 150 by 10 we get 15 jumps per hour. We know there are 60 minutes in 1 hour so lets convert that rate. We divide 15 by 60 to get .25 jumps per minute. We then do .25 times 12 to get 3. So the answer is 3 jumps in 12 minutes.
