220 miles to their vacation spot. They would like to complete the drive in
4
4 hours. Find the average speed in miles per hour needed to make the trip in the desired time.​

​Answer:
miles per hour.

Answer 1

To find the average speed needed to complete the trip, you can use the formula:

\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]

In this case, the total distance is 220 miles, and the total time is 4 hours.

Substituting the values into the formula, we get:

\[ \text{Average Speed} = \frac{220 \text{ miles}}{4 \text{ hours}} = 55 \text{ miles per hour} \]

So, the average speed needed to make the trip in the desired time is 55 miles per hour.
