Question

8. A train is moving at a uniform speed of 75km/hr.

i) How far will it travel in 27 minutes?
ii) In how much time will it cover in 210 km?​

Answer 1

Answer:

The whole sum is in S.I.unit .

speed = 75km/hr

changing in m/s

=75×1000/60×60 m/s

=125/6 m/s

time =27 minutes =27×60=1620 seconds

d=125/6×1620

d= 33750 m/s

distance =210km =210×1000

speed =125/6

time=distance/speed

=21000/125/6

= 10080sec =2.8hour
