Question

A boat travels $30km$ in $6hours$. Calculate the speed of the boat.

• A. $4km{h}^{-1}$
• B. $5km{h}^{-1}$
• C. $6km{h}^{-1}$
• D. $8km{h}^{-1}$

Answer 1

The correct option is B $5km{h}^{-1}$

Given:
Distance, $D=30km$
Time taken, $t=6hours$

By definition,
$\text{Speed}=\frac{\text{Distance}}{\text{Time~taken}}$
$v=\frac{D}{t}$
$v=\frac{30km}{6h}$ = $5km{h}^{-1}$
