Question

X and Y are two stations which are 320 miles apart. A train starts at a certain time
from X and travels towards Y at 70 mph. After 2 hours, another train starts from Y and
travels towards X at 20 mph. At what time do they meet?

Answer 1

Answer:

Distance traveled by train coming from Y in 2 hours=20×2=40 miles

They will meet at a distance of 320−40=280 miles from X

Time required to cover 280 miles by train coming from X

280/70=4h

Hence they meet after 4 hours.
