Question

a train at a uniform speed cover 420 km in 7/2 hours. find the speed of the train and the distance covered in 5 hours​

Answer 1

Hello Mate! Here is your answer:

Given,

Distance Covered (d) = 420 km

Time (t) = 7/2 hrs

= 3.5 hrs

Speed (S) = d/t

= 420/3.5 km/hr

= 120 km/hr

Time (t) = 5 hours

Distance Covered in 5 hours = S = d/t

= 120 = d/5

= 600 km = d

The Speed is 120 km/hr and the Distance Covered in 5 hours will be 600 km.

I hope this helps.

Answer 2

$Distance Covered (d) = 420 kmTime (t) = 7/2 hrs= 3.5 hrsSpeed (S) = d/t= 420/3.5 km/hr= 120 km/hrTime (t) = 5 hoursDistance Covered in 5 hours = S = d/t= 120 = d/5= 600 km = d$

hence dis is ur answer
