Answer:
Total time = 6.5 hrs
Let the total distance be x
Ramesh's speeds = 30, 45, 60 kmph
Speed, Time and Distance Questions with Answers (Part -3) Quant Notes | EduRev
or x = 270 km
With each speed distance covered = 270/3 = 90 km
Fuel consumed when driving at 30 = 90/11 = 8.1 l
Fuel consumed when driving at 45 = 90/14 = 6.4 l
Fuel consumed when driving at 60 = 90/18 = 5
Total fuel = 8.1 + 6.4 + 5 = 19.5 liters
When Arun drives the car, he should drive at 60 kmph throughout so that he gets the maximum mileage!
Fuel consumption when driving at 60 for entire journey = 270/18 = 15 liters
The question is " So he decides to drive Ramesh's car one day from city A to city B. How
much fuel will he be able to save? "
Difference = 19.5 – 15 = 4.5
Hence, the answer is 4.5 liters.
