A and B start from the same point and at the same time with speeds 15

1.	A and B start from the same point and at the same time with speeds 15 km/h and 12 km/h respectively, find the distance between A and B after 6 hours if both move in :(i) same direction(ii) the opposite directions.
Answer» A’s speed = 15 km/h B’s speed = 12 km/h Distance covered by A in 6 hours = 15 x 6 = 90 km and Distance covered by B in 6 hours = 12 x 6 = 72 km (i) Distance between A and B when they move in the same direction = 90 – 72 = 18 km (ii) Distance between A and B, when they move in the opposite directions = 90 + 72 = 162 km

A and B start from the same point and at the same time with speeds 15 km/h and 12 km/h respectively, find the distance between A and B after 6 hours if both move in :(i) same direction(ii) the opposite directions.

Answer»

A’s speed = 15 km/h

B’s speed = 12 km/h

Distance covered by A in 6 hours = 15 x 6 = 90 km

and Distance covered by B in 6 hours = 12 x 6 = 72 km

(i) Distance between A and B when they move in the same direction = 90 – 72 = 18 km

(ii) Distance between A and B, when they move in the opposite directions = 90 + 72 = 162 km
