Two trains start at the same time from opposite ends of
a 300 km track. Their speeds are 70 and 80 km/h. When they meet, how far is the faster train from the slower’s starting point?Solution

They meet after t = 300/(70+80)=300/150=2 hrs Faster train covers 80×2=160 km from its end ⇒ from slower’s start = 300–160 = 140 km.
