If a person travels $60\ km$ in $4$ hours in a car, then the speed of the car is:
- A$12\frac{\text{km}}{\text{hr}}$
- ✓$15\frac{\text{km}}{\text{hr}}$

Answer
View full question & answer→Correct option: B.
$15\frac{\text{km}}{\text{hr}}$
As, the distance travelled by the car in $4$ hours $= 60\ km$
$\Rightarrow $ The distance travelled by the car in $1$ hour $=\frac{60}{4}=15\text{km}$
So, the speed of the car is $15\frac{\text{km}}{\text{hr}}$.
Hence, the correct alternative is option $(b).$
