Question:

A man walks 4 km towards north in one hour and 3 km towards east in the next hour. What is his average speed?

Solution:

By the definition, the formula for average speed looks like:

$$v_{avg} = \frac{\text{Total Distance Covered}}{\text{Total Time Taken}} = \frac{4km + 3km}{1hour + 1hour} = \frac{7km}{2hour} = 3.5 \frac{km}{hour}.$$

Answer:

$$v_{avg} = 3.5 \frac{km}{hour}.$$
