They said the speed of the bus is x.
time = distance/speed. So,
280/x = 280/(x+20) + 7/6
The distance between towns M and N is 280 km. A car and a bus travel from M to N.
The average speed of the bus is 20 km/h less than that of the car. The bus takes 1 h 10 min more than the car to travel from M and N.
(a) If the speed of the bus x km/h ?
car = x
bus x - 20 + 1 1/6
