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!
Brainliest is appreciated if you feel its deserved. :)
