Answer 1

ANS

We are given that a fast train covers 360 km in 3 hours 20 minutes.

We have to calculate the time it will take to cover a distance of 90 km.

Speed is the ratio of total distance travelled to the time taken to travel this distance.

Train travels 360 km in 3 hours 20 minutes.

1 hour will have 60 minutes.

3 hours will have 3×60=1803×60=180 minutes.

3 hours 20 minutes will have 180+20=200180+20=200 minutes.

Therefore, the train travels 360 km in 200 minutes.

speed=disttimedist=360km,time=200min⇒speed=360200⇒speed=95km/minspeed=disttimedist=360km,time=200min⇒speed=360200⇒speed=95km/min

Train travels 90 km and we have to calculate the time taken by the train to travel 90 km.

time=distspeedspeed=95km/min,dist=90km⇒time=90(95)=90×59=10×5⇒time=50mintime=distspeedspeed=95km/min,dist=90km⇒time=90(95)=90×59=10×5⇒time=50min

Therefore, the fast train takes 50 min to cover a distance of 90 km.
