I need help with this 7th grade math equation

Question

Charles is going camping with his family. Their campsite is 3/4 mile away. They walk at a steady speed of 1 and 1/4 mi/h How many minutes will it take them to get to the​ campsite?

Answer 1

Kathrine, this is an example of

distance = rate * time

You have values for distance and rate (speed), so you need to solve for time.

divide both sides of the equals dign by rate

distance / rate = time

so put the numbers in for these names

3/4 mile / 1 1/4 miles per hour = time

Notice that the result will be a fraction of an hour. So convert it to minutes by multiplying by 60.

(60 * 3/4) / (1 1/4)

Fractions are tedious, I know, but 7th grade can handle them, I think. If not, ask another question.
