Question

If the speed of train is 92.4 kmph how many metres would it cover in 20minutes

Answer 1

in meter per minute → 92.4*1000/60= 1540m/min
so in 20 min
distance covered=d= 1540*20=30800m

Answer 2

the formula 
                  S=D/T
                   92400mph=D/1200s
                   D=92400x1200
                    D=110880000M
