Question

A person briskly walked 5.00 meters to the east and then 3.00 meters to the west in a total of 4.00 seconds. What was their speed?

Answer 1

By definiton, the average speed is equal to the total travelled path divided by total time spent. Thus, obtain:

$$v =\dfrac{5m+3m}{4s} = 2m/s$$

Answer. 2 m/s.
