Verified Answer

Chandan travelled equal distance with speed of 3 km/hr, 4 km/hr and 8 ...

Let the total distance be ‘x’ km.
Chandan travelled equal distance.
⇒ He travelled (x/3) km each time.
We know that,
Time = Distance/Speed
⇒ Total time taken = [(x/3)/3] + [(x/3)/4] + [(x/3)/8]
⇒ 42.5 min = (x/9) + (x/12) + (x/24)
⇒ 42.5/60 = 17x/72 (∵ 1 hr = 60 min)
⇒ x = (17/24) × (72/17) = 3 km
∴ The total distance = 3 km

Similar Railways Doubts

On a 20 km tunnel connecting two cities A and B, there are three gutters. The distance between gutters 1 and 2 is half the distance between gutters 2 and 3. The distance from city A to its nearest gutter, gutter 1 is equal to the distance of city B from gutter 3. On a particular day the hospital in city A receives information that an accident has happened at the third gutter. The victim can be saved only if an operation is started within 40 minutes. An ambulance started from city A at 30 km/hr and crossed the first gutter after 5 minutes. If the driver had doubled the speed after that, what is the maximum amount of time the doctor would get to attend the patient at the hospital.
