hey buddy,
let us suppose that the distance travelled will be 200 km ( LCM of 50 and 40)
so their time taken will be:
200/50 = 4 hours
200/40 = 5 hours
so total time taken will be 9 hours
and total distance will be 200 + 200 = 400 km
so average speed will be = 400/9 = 44.44km/h
the displacement in this case is zero, therefore the average velocity will also be zero
