Medium Open in App Solution Verified by Toppr Given

Jagan covered 240 km distance by a car at 60 km/h

He travelled 80 km distance by train at 100 km/h

He travelled 200 km distance by a bus at 50 km/h

Hence,

Total distance travelled by Jagan =240km+80km+200km

=520km

Now, total time taken by during whole journey is shown below

Time taken by car =240km/60km/h

=4 hours

Time taken by a train =80km/100km/h

=4/5 hours

Time taken by bus =200km/50km/h

=4 hours

So, total time taken =4+4/5+4

=(20+4+20)/5 We get, =44/5 hours Hence,

Average speed = total distance / total time

=520km/(44/5) hours =[(520×5)/44]km/h =(130×5)/11km/h =650/11km/h =59 11 1 ​ km/h

Hence, the average speed during the whole journey is

59 11 1 ​ km/h

15 Q:

Jagan went to another town covering 240 km by car moving at 60 kmph. Then he covered 400km by train moving at 100 kmph and then rest 200 km he covered by a bus moving at 50 kmph. The average speed during the whole journey was ?

A) 36 kmph B) 35 kmph

C) 72 kmph D) 70 kmph

Answer:   D) 70 kmph

Explanation:

By car 240 km at 60 kmph

Time taken = 240/60 = 4 hr.

By train 240 km at 60 kmph

Time taken = 400/100 = 4 hr.

By bus 240 km at 60 kmph

Time taken = 200/50 = 4 hr.

So total time = 4 + 4 + 4 = 12 hr.

and total speed = 240+400+200 = 840 km

Average speed of the whole journey = 840/12 = 70 kmph.
