Question 771275


The distance between delhi and meerut is 75 km.Two trains at a speed of 100km/hr & 80km/hr leave the two stations at 8 am towards eachother.At what time will they pass eachother?


Let time it’ll take them to meet be T
Distance equation: Distance covered by faster train, plus distance covered by slower train, equals distance between the two stations, OR
100T + 80T = 75
180T = 75


T, or time = {{{75/180}}} hr, or 25 minutes


Time they’ll pass each other = {{{highlight_green(8:25)}}} AM


You can do the check!!
