Question

Sohail cycles on a circular track in anticlockwise direction as shown in figure. He travels with a speed ‘V’ to cover the path AB, next with speed ‘2V’ from B to C and with a speed of ‘3V’ from C to A. What is his average speed for the total journey?

• A. $2V$
• B. $6V$
• C. $3V$
• D. $\frac{V}{2}$

Answer 1

The correct option is A

$2V$

In this case, as the speed is given, so
Average Speed $=\frac{\text{Total speed}}{3}$
$=\frac{V+2V+3V}{3}=2V$
