Best ResponseYou've already chosen the best response.1@mr.tobby Both the cases the distance is the same, Let time taken usually be t hours First case the bus arrives half an hour late. So time taken by it (t+0.5) hours Second case the bus arrives half an hour early. Time taken (t0.5) hours Distance covered in first case \[D=36(t+0.5)\] Distance covered in second case \[D=42(t0.5)\] Equate both these \[36(t+0.5)=42(t0.5)\] Can you find t from this ? @mr.tobby
