Question 6: Travelling at 6 kmph, mayur reaches her office 20 minutes late. Travelling at 8 kmph, he reaches his office 30 minutes early. What is his usual speed and time taken to reach her office? Solution: Let her usual speed be S kmph and her usual time be t hours Therefore, Solving for t, we get t = 3 hrs Since the usual time taken = 3 hrs, usual distance travelled = 3S kms Equating distance travelled usually, with distance travelled at any of the other two speeds, we get 6 * (3+20/60) = 3S Therefore, S = 6 kmph
