(2) Let speed of bus = x km/h and speed of car = (x + 25) km/h Also, distance = 500 km Then, according to the question,
500
x
−
500
x+25
= 10 ⇒ 500 (x + 25 - x ) = 10(x) (x + 25) ⇒ x (x + 25) = 25 x 50 ⇒ x = 25 km/h and (x + 25) = 25+ 25= 50 km/h Hence, speeds of the car and the bus are 50 km/h and 25 km/h respectively.
