Question

(13.) A train is booked to do the run between two places, 55 km apart, in 1 hr 20 min. If it travels for the first
30 km at 36 km per hour, at what speed must it travel for the rest of the distance in order to complete
the journey in time?​

Answer 1

Answer:

50km/hr

Step-by-step explanation:

36x=60 minutes. (x=5/3)

30x= how many minutes

so 30x= 50 mins

hence 30 mins are left for remaining 25 kms so the required speed is

25km/half hour

which is also equal to 50km/hr

hence the answer is 50 km/hr
