Question
'Aβ and βBβ started moving towards each other at
same time with a speed of 8 km/hr and 10 km/hr, respectively. If the distance covered by βAβ is 15 km more than that by βBβ, when they meet then find the initial distance between them.Solution
Ratio of distance travelled by βAβ and βBβ = 8:10 = 4:5 Required distance = 15 Γ 9 = 135 km
