One of my friend was going from my hometown, Kaithal to Karnal, with a full tank of gasoline i.e. 23 gallons.
But unfortunately, at that exact moment his gasoline tank sprang a leak, due to which he started losing 1 gallon of fuel each hour.
When going to Karnal which is 60 kms away, he could only manage a speed of 12 kmph.
But on the way back to Kaithal, he managed a speed of 16 kmph.
(He was travelling at 8 kms per gallon)
Were 23 gallons enough for the round trip ??
If not, how much more gallons, he needs ??
Difficulty Level - 3/5
