Question
Two trucks, ‘P’ and ‘Q’, start from locations
‘U’ and ‘V’ respectively, moving towards each other at the same time. After 10 hours they meet, and truck ‘Q’ has covered 180 km more than truck ‘P’. If the total distance between U and V is 780 km, how far did truck ‘P’ go in 6 hours?Solution
ATQ,
Let distance travelled by truck ‘P’ = ‘x’ km
Then, distance travelled by truck ‘Q’ = ‘x + 180’ km
According to question;
x + x + 180 = 780
Or, 2x = 600
Or, x = 300
Distance travelled by truck ‘P’ in 10 hours = 300 km
Speed of truck ‘P’ = 300 / 10 = 30 km/h
Distance travelled by truck ‘P’ in 6 hours = 30 × 6 = 180 km
