Question

A train travels a distance of 1000 km 400 m in 15 1 /2 hours 30 minutes what is the average speed of the train

Answer 1

distance is 1000 km 400 m

so , distance is [1 km =1000m]

then it is 1000400 m

time is 15 and 1/2 hour 30 min

so , time is [ 1 hour = 60 min ]

then it is 15*60+1/2*60+30

900+30+30

960 minutes

average speed = total distance / total time taken

s = 100400/960

s= 104.58 metre per minute
