Question Of The Day

    I was travelling from Pune to Bombay when I met 5 of my friends at an intermediate station, Lonavia. Everybody crammed into my car, as a result of which the speed of my car reduced by 20% and I reaches Bombay 45 minutes later than I expected to. If I had taken 1 hour to reach Lonavia at a speed of 30 kmph, what is the distance from Bombay to Pune, assuming that I drive at a constant speed?  

    a) 200 km

    b) 150 km

    c)  90 km

    d) 120 km

     

    Ans: d) 120 km

     

    If my speed reduced by 20%, i.e. became 4/5th, then I take the original time required. ∴ 1/4th time extra is 45 min., or the original expected time from Lonavia to Bombay is (45)(4) = 180 min = 3 hr. ∴ Original expected time from Pune to Bombay is (3 + 1) = 4 hr. if this was at 30 kmph, distance = 120 km.
