Two people are 16km apart on a straight road. They start walking at the same time. If they walk towards each other, they will meet in 2 hours, but if they walk in the same direction (so that the distance between them is decreasing), they will meet in 8 hours. Find their walking speeds.

Respuesta :

Answer:

Their working speed = 5 km/ hour and 3 km/ hour

Explanation:

Let their speeds be x and y

2 ( x+y) =16

x+y = 8 .....................(A)

Assuming x is > y

8x- 8y = 16

x- y = 2 ................(B)

(A) + (B) 2x = 10

x = 5 km/ hour y = 3 km/ hour
