The speed of a bus is 72 kmph. The distance covered by the bus in 5 sec is
(a)50 m
(b)74.5 m
(c)100 m
(d)60 m
Answer
Answer (as printed): C
Explanation
Speed of bus $=72 \mathrm{km} / \mathrm{ph}=\left(\frac{72 \times 5}{18}\right) \mathrm{m} / \mathrm{sec} .=20 \mathrm{m} / \mathrm{sec}$. Let distance covered by bus in 5 sec be $x$ ∴ Distance = Speed × Time $\Rightarrow x=20 \times 5=100$ meter
