In 1/2 an hour, Josh ran 3/4 a mile. How many miles would Josh run in one hour?

1.5 miles

Step-by-step explanation:

We can make a proportion to solve

He runs 3/4 or 0.75 miles in 1/2 or 0.5 hours, and he runs x miles in 1 hour

0.75/0.5=x/1

Cross multiply

0.75*1=0.5*x

0.75=0.5x

We need to solve for x. To do this, we have to get x by itself. x is being multiplied by 0.5. To undo this, divide both sides by 0.5

0.75/0.5=0.5x/0.5

1.5=x

In 1 hour, he runs 1.5 miles
