Q) Two people are 16 km apart on a straight road. They start walking at the same time. If they walk towards each other with different speeds, they will meet in 2 hours. Had they walked in the same direction with same speeds as before, they would have met in 8 hours. Find their walking speeds.
Ans: Let their speeds x and y kmph.
Walking in same direction: x – y = = 8………….(i)
Similarly, when they walk in opposite directions, x + y = = 2.
by solving equations (i) and (ii), we get:
x = 5 and y = 3
Therefore the walking speeds are 5 km/hr and 3 km/hr.
