Question

A man takes $150$ steps in walking $120$ meters. If he takes $3$ steps in one second, then his speed in m/s is equal to

• A. $2.4$
• B. $3.2$
• C. $7.5$
• D. $1.5$

Answer 1

The correct option is A $2.4$

Speed of man = 3 steps per second.

Therefore, time taken by man in 150 steps = $\frac{150}{3}=50$ sec.

$Speed=\frac{Distance}{Time}=\frac{120}{50}=2.4m/s$
