Question

A man cycles from his house to the market 5 km away taking 10 minutes. He then turns and
returns home taking 20 minutes. Explain the difference between average speed and average
velocity with this example?​

Answer 1

Answer:

When speed is 30 km/hr he reaches 10 minutes late when Speed is 40 km/hr he reaches 5 minutes earlier.

Let Distance be D and T=D/S

D/30 - D/40 = 15 min or 15/60hr

4D - 3D/120 = 15/60

D = 30Km
