Given : Two cars leave town at the same time and travel in the opposite directions. The speed of one car is 12km/h more than the other. They are 444km apart after 3 hours
To find : Speed of Each Car
Solution:
Let say Speed of one Car = C km/Hr
Speed of Another Car = C + 12 km/hr
Using Formula Distance = Speed * Time
Distance Covered by one Car in 3 hrs = 3C km
Distance Covered by Another Car in 3 hrs = 3(C + 12) = 3C + 36 km
As Car are moving in opposite direction
=> Total Distance between Cars = 3C + 3C + 36 km
= 6C + 36 km
= 6(C + 6) km
6(C + 6) = 444
=> C + 6 = 74
=> C = 68
C + 12 = 80
Speed of Cars = 68 km/hr & 80 km/Hr
