Answer 1

Step-by-step explanation:

time at which train left delhi :- 19:15 hours

time at which it ariived Mathura:- 22:05 hours

time taken by train ;- 22:05 - 19;15 = 4 hours 50 minutes (0290 hours) = 4 50/60 = 4 5 /6

distance :- 144 km

speed = distance ÷ time

speed = 144 ÷ 4 5/6

= 29.7931034 km / hr

Answer 2

Answer:

13 m/s

Step-by-step explanation:

Time at which the train left : 19 hours 15 minutes

Time at which the train arrived: 22 hours 5 minutes

Time taken to travel : 22:05 hours - 19:15 hours

                                   2 hour 50 minutes

Time taken in seconds : (2*3600) + (50*6)

                                          7200 + 300

                                          7500 seconds

Total Distance : 144 km

Total Distance in meter : (144*1000)

                                         144000 meters

SPEED = DISTANCE ÷ TIME

            = 144000 ÷ 7500

            = 1440 ÷ 75

            = 299 ÷ 13

            = 13 m/s
