Chen can jump rope 60 times a minute. at that rate ,how many jumps can he make in 9 minutes

Answer is 540 jumps.

Hey,

In this situation we are given the information that Chen can jump 60 times a minute.

And we are asked how many times can he jump in 9 minutes.

Given 1 minute consists of 60 seconds. And Chen jumps 60 times in one minute. To find how many jumps a second he has we can do. 

60 divided by 60.

This equals to 1. And therefore we can conclude that he can jump 1 time per second. And sixty seconds in a minute. He jumps 60 times in one Minute.

Now we can take this and multiply the 60 times he jumps in 1 minute and multiply it by 9 to find how many times he can jump in 9 minutes.

As so:

60 x 9 = 540 jumps in 9 minutes

Meaning Chen can jump 540 times in 9 minutes.

I do hope this helps!
