Question

A train travels at a certain average speed for a distance of 63 km and then Travels at a distance of 72 km at an average speed of 6 km per hour more than its original speed if it takes 3 hours to complete the total journey what is the original average speed

Answer 1

1st let the average speed of the train is =x
now speed =distance/time hence, 63/x
again for covering the distance of 72 k.m.
the time= 72/x+6
now 63/x+72/x+6=3 hours
now solve the equation to get the answer
ans:-42
