Question

Riaz takes$20$ a min to travel to his school at a speed of$3m/s$.

How far is the school?

• A. $2$ km
• B. $3.2$ km
• C. $\mathbf{3}\mathbf{.}\mathbf{6}\mathbf{}$km
• D. $4.1$km

Answer 1

The correct option is C

$\mathbf{3}\mathbf{.}\mathbf{6}\mathbf{}$km

Given speed $=3m/s$

Time$=20$ min $=20\times 60=1200s$

Distance = speed × time$=3\times 1200=3600$ m

$=3.6$km

Hence, option (C) is the answer.
