a plane that travels 1400 miles during a 2 1/2-hour flight. How many miles per hour, on average, does the plane travel?

Answer 1

To calculate the average speed of the plane, we need to divide the total distance traveled by the total time taken.

First, let's convert the time of 2 1/2 hours to a decimal format. If we express the fraction as a decimal, we have:

2 + 1/2 = 2 + 0.5 = 2.5 hours

Next, we divide the distance of 1400 miles by the time of 2.5 hours:

Average speed = distance/time = 1400 miles / 2.5 hours

Performing the division, we get:
Average speed = 560 miles per hour

So, on average, the plane travels at a speed of 560 miles per hour.
