Question

Adam solved 12 math problems in 42 minutes. If he continues at this pace how many minutes will it take him to solve 20 math problems?

Answer 1

Explanation:

To find out how long it will take Adam to solve 20 math problems at the same pace, you can set up a proportion based on the given information:

12 math problems / 42 minutes = 20 math problems / x minutes

Now, you can solve for x (the time it will take to solve 20 math problems):

12/42 = 20/x

To isolate x, you can cross-multiply:

12x = 42 * 20

Now, divide both sides by 12 to solve for x:

x = (42 * 20) / 12

x = 70 minutes

So, it will take Adam 70 minutes to solve 20 math problems at the same pace.
