Question

Mr.Sam took 1 h and 15 min to drive from his home to office. If the distance between his home and office was 50 miles, at what average speed did Mr. Sam drive?

Answer 1

The average speed at which Mr. Sam drove is 40 mph (miles per hour)

Step-by-step explanation:

Speed ​​is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, speed is associated with the change in position of a body over time.

Speed ​​can be defined as the amount of space traveled per unit of time with which a body moves in a certain direction and direction:

`Speed=(distance traveled by an object)/(time)`

In this case:

• distance traveled by an object: 50 miles
• time: 1 h 15 min (1 h=60 minutes, so 1 h 15 min= 75 min. Thus 1 h 15 min= 1.25 h)

Replacing:

`speed=(50 miles)/(1.25 h)`

speed = 40 mph

The average speed at which Mr. Sam drove is 40 mph (miles per hour)
