Question

5- It takes 42 minutes to walk eastward along a road to a store 2.3 km away. What is the average velocity?

Answer 1

Answer:

It takes 42 minutes to walk eastward along a road to a store 2.3 km away.

Distance, d = 2.3 km

Time taken, t = 42 min = 42/60 hr

The average velocity is,

$v = \frac{d}{t} \\ v = \frac{2.3 \times 60}{42} \\ v = \frac{23 \times 10}{7} = 32.857 \: \: \frac{km}{hr}$
