Question	A farmer travelled from his village to city to buy seeds. He went by bicycle at a speed of 20 km/hr and came back at a speed of 5 km/hr. If the farmer took 5 hours and 40 minutes to complete his journey, find the distance between village and city?
Type	multiple_choice
Option	15 km	incorrect
Option	19 km	correct
Option	23 km	incorrect
Option	25 km	incorrect

Solution :

Total distance travelled = Average speed * Total time taken to complete the journey

Average speed =

Total time taken = 4 hour 45 minutes =²⁸⁵⁄₆₀ =¹⁹⁄₄hour

So, Total distance travelled = 8 *¹⁹⁄₄= 38 km

Distance between village and city will be half of the total distance travelled: So, distance between village and city =³⁸⁄₂ = 19 km (Option B)
