Answer 2

Hey there!

Here is your answer:

Given places Aand B are 100km apart

CASE 1:They start travelling in the same direction at different speeds and they meet in 5hours.This statement means that the difference between the distance covered by the first car and the second car is 100km

Distance= speed*time

Let the speed of first car and the second car be x & y respectively

Time = 5hours

Equation: 5x-5y=100

or x-y=20----------(1)

CASE 2: Both the cars are travelling towards each other and they meet in 1 hour..which means the sum of the distance covered by the 2 cars is 100km

Distance= speed*time

Time= I hour

Equation= 1x+1y=100

or x+y=100------------(2)

Adding equations (1) and (2) we get,

X+y=100

X-y=20

==> X=60

Speed of the first car = 60km/h

==>Y=100-60=40

Speed of the second car=40km/h
