Question
Two individuals, P and Q, set off from points X and Y
simultaneously, moving toward each other. P travels at a speed of 60 km/h, while Q moves at 40 km/h. By the time they meet, P has covered a distance that is (d + 60) km greater than the distance covered by Q. Given that the total distance between X and Y is 720 km, determine the value of 'd'.Solution
ATQ,
Time taken by them to travel before they meet = 720/(60 + 40) = 7.2 hours According to question, 7.2[60 – 40] = (d + 60) 7.2 × 20 = (d + 60) 144 = (d + 60) d = 144 – 60, d = 84
