Question

two automobile start time from cities 595 km apart . if the one is 8/9 of the speed of the other and if they meet in 7 hour , what is the speed of each

Answer 1

Answer: 45km/hr and 50km/hr

Step-by-step explanation:

Let the speed of both trains be x and

8x/9.

After travelling 7hrs, speed of each train = 7x km/hr and 7(8x/9)km/hr

ATQ, 7x + 56x/9 = 595

(63x + 56x)/9 = 595

115x/9 = 595

115x = 595*9

115x = 5355

x = 5355/115 = 45

Hence, speed of trains are 45km/hr and (8/9 * 45) = 40km/hr.

Hope it helps.
