Which is costlier ?

Question

I travel a distance of 'x' kms on my bike at a speed of 50kmph. If I cover the same distance at a speed of 60kmph, which costs me more.. i mean by which speed my bike uses more petrol ?

Answer 1

The faster you go, the more gas you use.  

Also, gas mileage decreases rapidly at speeds above 60 mph. Each mph driven over 60 will result in an additional waste of 10 cents per gallon. To maintain a constant speed on the highway, use cruise control.

60 miles = 96.5606400000519 km
