Two trains leave towns 1490 kilometers apart at the same time and travel toward each other. One train travels 20 km/h slower than the other. If they meet in 5 hours, what is the rate of each train?


Sagot :

Answer:143 km/h

159 km/h

Step-by-step explanation: The 1208 km separation distance is closed in 4 hours, so the rate of closure is ...

 (1208 km)/(4 h) = 302 km/h

If s represents the speed of the slower train, then the sum of their speeds is ...

 s + (s+16) = 302

 2s = 286

 s = 143

 s+16 = 159
