Owen: 5x + 6y = $28.75
kayden; 4x + 3y= $16.25
that’s all i know, sorry
The faster train overtake the slower on 5 p.m.
How to solve such time related questions?
The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed x Time.
Let the number of hours after 1pm at which faster train will overtake slower train be x.
At overtaking point,
Distance travelled by slower train = Distance travelled by faster train
Given :
- Speed of slower train = 40 miles per hour
- Speed of faster train = 60 miles per hour
- Time taken by faster train = x
- Time taken by slower train = x + 2.
On equating distances we get
40 x ( x + 20) = 60 x (x)
40x + 80 = 60x
20x = 80
x = 4.
∴The faster train overtake the slower on 1 + 4 = 5 p.m.
