Explanation:
let they meet at X point between ambala and delhi
distance travelled by car A = X
speed of car A = 30 km/ hr
time = X÷30
distance travelled by car B = 200 - X
speed of car = 20 km/hr
time = (200-X) ÷ 20
time is equal in both cases as cars start travelling at the same time
(200-X)÷20 = X÷30
X comes out to be 120 km
the distance from ambala is 120 km
