 Question 253766: In the time it takes one car to travel 93 km, a second car travels 111 km. If the average speed of the second car is 12 km/h faster than the speed of the first car, what is the speed of the car?Answer by palanisamy(496)   (Show Source): You can put this solution on YOUR website!Let the speed of the first car be x km/h Then the speed of the second car = x+12 Time taken by tne first car to travel 93kms = 93/x Time taken by tne second car to travel 111 kms = 111/(x+12) Given, both times are equal. 93/x = 111/(x+12) 93*(x+12) = 111x 93x+1116 = 111x 1116 = 111x-93x 1116 = 18x x = 1116/18 x = 62 So the speed of the first car is 62 kms/h and the speed of the second car is 62+12 = 74 kms/h
