Question

1) A train is travelling at a uniform speed of 120km/h. How long will it

take to cover a distance of 480km.



5) A train travelling at uniform speed of 15000 m/s. Express this in km/h




​

Answer 1

Answer:

1) it will take 4 hrs to cover 480km distance, as it is said it is moving uniformly and its speed is 120km/h. (120km/h x 4 = 480km/4hrs)

2)for this u can just simply multiply the fraction into 3.6

then u will get 4166.66km/h

Answer 2

Answer:

1) speed of the train = 120km/h

  distance to cover = 480km

  time needed to cover = distance / speed

 

  = 480 / 120

  = 4 hours

2) 1 km = 1000 m

 

   15000 m = 15000 / 1000

   = 15 km/h
