Complete question :
Two trains leave towns 1180 kilometers apart at the same time and travel toward each other. One train travels 19km/hr slower than the other. If they meet in 4 hours, what is the rate of each train
Answer:
138 km/hr ; 157 km/hr
Explanation:
Distance apart, d = 1180
Let :
Speed of A = x
Speed of A, = x - 19
Meeting time = 4 hours
Distance covered by A + Distance covered by B = total distance
Distance = speed * time
4 * (x - 19) + (4 * x) = 1180
4x - 76 + 4x = 1180
8x = 1180 + 76
8x = 1256
x = 1256 / 8
x = 157 km/hr
Speed of other train : (x - 19) = 157 - 19 = 138 km/hr
