Question

jagrit drove home at an average speed of 60km/hr for a journey of 20km if he wanted to reach minutes earlier at what average speed should he drive

Answer 1

If he wanted to reach minutes earlier so his speed should be 80 km /hr.

Step-by-step explanation:

Average of Jagrit = 60km/hr

Distance of journey = 20 km

$Time = \frac{Distance}{Speed}$

$Time = \frac{20}{60}$

He wanted to reach 5 minutes earlier

60 minutes = 1 hour

1 minute = $\frac{1}{60}$

5 minute = $\frac{5}{60}$

If he reach 5 minutes earlier then time taken =  $\frac{20}{60}-\frac{5}{60}=\frac{15}{60}$

Distance of journey = 20 km

Time = $\frac{15}{60}$

$Speed = \frac{Distance}{Time}$

$Speed = \frac{20}{\frac{15}{60}}$

$Speed = 80$

Hence if he wanted to reach minutes earlier so his speed should be 80 km /hr.
