Question

A car travels a distance of 258 km in 3 hours 5 minutes. what is the speed of the car?

Answer 1

Speed = $\frac{Distance}{time}=\frac{258\times {10}^3}{(3\times 3600)+(5\times 60)}\frac{m}{sec}$

$=\frac{258}{(3\times 3.6)+(30\times {10}^{-2})}$ $=\frac{258}{10.8+0.3}=\frac{258}{11.1}=23.24m/s$
