Plane A flew 225 miles in two hours, while plane B flew 300 miles in three hours. Which plane had the faster rate, miles per hour?

Let’s break down the information that we know. Plane A flew 225 miles in two hours. Plane B flew 300 miles in three hours. The key to solving this problem is finding the miles per hour, the miles they went every hour.

To find the rate, we we’ll take the distance and divide it by the time. For plane A, that would be 225 divided by two. And for plane B, that would be 300 divided by three. 225 divided by two equals 112 and half, 112.5. 300 divided by three is easily recognizable as 100.

Because we’re working with miles and hours, our rate is shown in miles per hour. 300 miles divided by three hours equals 100 miles per hour. 225 miles divided by two hours equals 112 and half miles per hour.

But back to the question at hand, the question at hand says which plane had the faster rate? Plane A was just a little bit faster than plane B.

Plane A flew 112 and a half miles per hour, while plane B only flew 100 miles per hour. Plane A had the faster rate.
