Question
Two trucks βMβ and βNβ started simultaneously
from cities βXβ and βYβ respectively towards each other. When they met after 9 hours, truck βNβ had travelled 144 km more than truck βMβ. How much distance did truck βMβ travel in 6 hours if the total distance between X and Y is 624 km?Solution
ATQ,
Let distance travelled by truck βMβ at the time of meet = x km
So, distance travelled by truck βNβ at the time of meet = x + 144 km
According to question;
x + x + 144 = 624
Or, 2x = 480
Or, x = 240
Distance travelled by truck βMβ in 9 hours = 240 km
Speed of truck βMβ = 240 / 9 = 26.67 km/h
Distance travelled by truck βMβ in 6 hours = 26.67 Γ 6 = 160 km
