Question

A train is moving with velocity of 60 km/h. Calculate the distance travelled in 1 hr, 1 min, 1 second​

Answer 1

Explanation:

velocity V=60km/h

d=?

change time (hr to s)

case(i)v=60km/h. time t=1hr

distance=velocity *time

=60*1

=60km/h

case(ii)v=60km/h.time t=1min=1/60hr

d=v*t

=60*1/60

=1km/h

case(iii)v=60km/h.time t=1s=1/3600hr

d=v*t

=60*1/3600

=1/60

=0.016km/h

(or)change diatance(km/h to m/s)

case(i)v=60*5/18m/s=60.t=3600s

d=v*t

=30/18*3600

= 6000m/s

case(ii)v=60*5/18m/s.t=60s

d=v*t

=30/18*60

=600m/s

case(iii)v=60*5/18m/s.t=1s

d=v*t

=30/18*1

=1.6m/s
