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?

Answers

The required average speed to reach the school is 2.65 miles per minute.

Given that,
School starts in 45 minutes and you live 17 miles from school.
To determine at what average speed (in miles per hour) you need to travel in order to arrive at school on time.

What is speed?

Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.

What is average?

The average of the values is the ratio of the total sum of values to the number of values.

Here,
Distance = 17 miles
Time = 45 minutes

Speed = distance  / time
Speed = 45 / 17
Speed = 2.65 miles per minute

Thus, the required average speed to reach the school is 2.65 miles per minute.
