Question 22
Two trains one from station P to Q, the other from station Q to P start simultaneously with speeds 80 km/h and 95 km/h. If they meet after 12 hours, what is the difference between the distances covered by them?
Solution
let the distance between the train = D km
Relative speed by the two train = (95 - 80)km\hr = 15 km\hr
time taken to meet = $$\frac{D}{15}$$
12 hr = $$\frac{D}{15}$$
D = 180 km
