Question

In how much time will a train moving at a speed of 80 km/h cover a distance of 15 km?

Answer 1

Answer:

11.25 minutes

Step-by-step explanation:

Suppose the train will take x seconds

Given speed = 80km/hr

Speed of train  (in m/sec) = 8000m/3600s            (km in metre & hr in seconds)

                                    = 2.222m/sec

Now,

Distance = 15 km = 1500m

Speed = 2.222m/sec

Time = x sec               (as stated above)

We all know,

Distance = Speed*Time

1500 = 2.222 * x

x = 1500/2.222

   = 675.067 seconds

   = 11.25 minutes                      (converting seconds in minutes)
