Question

Is 22 miles in 20 minutes greater than, equal to or less than 38 miles in 30 minutes?

Answer 1

ANSWER

22 miles in 20 minutes is LESS

EXPLANATION

We want to compare the two rates:

=> 22 miles in 20 minutes

=> 38 miles in 30 minutes

To do this, let us simplify each rate by finding the speed, which is distance divided by time.

That is:

$s=\frac{\text{distance}}{\text{time}}$

For the first one:

$s=\frac{22}{20}=1.1\text{ mi/min}$

For the second one:

$s=\frac{38}{30}=1.27\text{ mi/min}$

Since 1.1 is less than 1.27, 22 miles in 20 minutes is less than 38 miles in 30 minutes.
