You have to find how many lots of 3 minutes there are in 1 hour (60 minutes) and then multiply that by the 10 math problems

I Dont't Understand That @MeganKeeping

megankeeping · Answer

In 3 minutes she can do 10 problems.
You need to find how many problems she can do in 60 minutes.

megankeeping · Answer

60/3 = 20 so there are twenty lots of 3 minutes in 60 minutes
This means she can do twenty lots of ten problems in 60 minutes

anonymous · Answer

To find the answer you need to divide 10 by 3. And multiply that answer by 60
