Question

School starts in 45 minutes and you live 17 miles from school. What average speed (in miles per hour) do you need to travel in order to arrive at school on time?

Answer 1

To arrive at school on time, you need to travel at an average speed of approximately 22.67 miles per hour.

Step-by-step explanation:

To determine the average speed needed to arrive at school on time, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, the distance is 17 miles and the time we have is 45 minutes (which is equal to 0.75 hours). Plugging these values into the formula:

Average Speed = 17 miles / 0.75 hours = 22.67 miles per hour

Therefore, you would need to travel at an average speed of approximately 22.67 miles per hour to arrive at school on time.
