Answer:
Speed of the cars are 60 km/hr and 40 km/hr.
Step-by-step explanation:
Given: Distance between point A and B is 100 km
let car starting from point A is Car A and Car starting from point B is Car B.
To find: Speeds of the cars
let Speed of Car A is x km/hr.
Speed of Car B is y km/hr
According to the question, (using speed, distance, time formula)
5x - 5y = 100
x - y = 20 .......................(1)
x + y = 100 ....................(2)
Add equation (1) and (2),
2x = 120
x = 60
put this value in equation (2),
60 + y = 100
y = 40
Therefore, Speed of the cars are 60 km/hr and 40 km/hr.
