Question 239128
two trains head in the same direction on parallel tracks, but train e is 30 km in front of train f. If train e averages 42km/h and train f averages 60 km/h, how long will it take for the faster train to catch up with the slower
--------------
Train f is gaining on train e at 18 km/h (60 - 42)
30 km/18 km/hr = 5/3 hours
= 1 hr 40 mins
