Question

5. A family leaves for an evening walk around the neighborhood. They leave at 5 pm and return at 6 pm. They traveled a total of 2.5 miles. What is their average speed?

Answer 1

This question involves the concepts of average speed, distance, and time.

The average speed of the family is "2.5 mi/hr".

AVERAGE SPEED

The average speed is defined as the ratio of the total distance covered with the total time taken to cover it.

$v=\frac{s}{t}$

where,

• s = distance covered = 2.5 miles
• t = total time taken = 1 hour
• v = average speed = ?

Therefore,

$v=\frac{2.5\ mi}{1\ hr}$

v = 2.5 mi/hr
