Traveling 30 kilometers per hour, a train travels 10 kilometers in:

Question

I simply need an answer to my problem

Answer 1

v (speed) = d (distance) / t (time)

 

which is equivalent to:

 

t = d / v

 

So at a speed of 30 km/h and a distance of 10 km:

 

t = 10 (km) / 30 (km/h) = 1/3 hour = 20 minutes
