Question

A car takes $2hours$to reach a destination by traveling at a speed of $60\frac{km}{hr}$How long it will take when the car travels at the speed of $80\frac{km}{hr}$

Answer 1

Step-1: Find the distance covered by car in $2hours$

The distance covered in $1hour=$$60km$ ( As speed is $60\frac{km}{hr}$)

The distance covered in $2hours$$=60\times 2=$$120km$

Step-2: Find the time taken for the car to travel $120km$distance at the speed of $80\frac{km}{hr}$

The Time is taken for the car to travel $80km=1hour$ ( As speed is $80\frac{km}{hr}$)

The Time it takes for the car to travel $120km=\frac{120}{80}=$$1.5hours$

Hence, The Time taken for the car to travel $120km$ is $1.5hours$
