Question

A car travels 60 km in 1 hr 30 min. How long will it take to cover a distance of 100km at same speed

Answer 1

Answer:

Given: distance=60km , time=1hr,30min= 90mins Speed=d/t= 60/90=2/3 km per min To find time taken to cover a distance of 100km at speed 2/3kmpm, Time= distance÷speed =100÷2/3 =100×3/2 =150 mins

Answer 2

Given - Distance and time

Find - Time to cover 100 km distance

Solution - The time taken to cover a distance of 100km at the same speed is 2.5 hours.

The formula to be used is -

speed = distance/time

The time in hours = 1 + 0.5

Time in hours = 1.5

Calculating the speed of the car.

Speed = 60/1.5

Speed = 40 km/hr

Now, calculating time is taken to cover the distance of 100 km.

Time = distance/speed

Time = 100/40

Time = 2.5 hours

Therefore, the time taken to cover a distance of 100km at the same speed is 2.5 hours.
