Answer» LET speed of car be x km/hr. ⇒ Speed of bus = (x - 25) km/hr We KNOW that, Time = Distance/Speed According to question, [500/(x - 25)] - (500/x) = 10 ⇒ 500 × 25 = 10x(x - 25) (x - 25)x = 50 × 25 ⇒ x = 50 km/hr & x - 25 = 25 km/hr ∴ The DIFFERENCE between the speeds of the car and the bus car = 50 - 25 = 25 |
