Question

Okay, let's say back in my fleet-footed days (my twenties--when I was also forty pounds lighter! EEK!) I could run 3 miles in 18 minutes. Actually, my fastest time was 17:25--stud! Calculate my miles per hour for running 3 miles in 18 minutes. (Now I'm doing great to run 3 kilometers in 18 minutes!)

Answer 1

Answer:

Your velocity is 10 miles per hour.

Step-by-step explanation:

This can be solved as a simple rule of three problem.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

Here, our measures are:

- The distance you ran, in miles

- The time you spent running.

As the time increases, so does the distance, it means there is a direct relationship between the measures.

Each hour has 60 minutes. You ran 3 miles in 18 minutes. So how many miles you ran in 60 minutes?

3 miles - 18 minutes

x miles - 60 minutes

18x = 180

$x = \frac{180}{18}$

x = 10 miles.

Your velocity is 10 miles per hour.
