Question

A car runs for 4 h every day and consumes 6.5 L of oil each hour. If the total oil consumption is 133.9 L, then for how many days does the car run in total?

• A. 4.33 days
• B. 5.15 days
• C. 6.55 days
• D. 7.12 days

Answer 1

The correct option is B 5.15 days

Oil consumed by car in one day = 6.5 L
In one day, the car runs for 4 h.

So, total consumption of oil by the car in one day = (6.5 $\times$ 4) L

Multiplying 6.5 $\times$ 4 by standard method, we get:


So, in one day, car consumes 26 L of oil.

Total volume of consumption of oil by the car = 133.9 L

∴ Number of days for which the car runs = 133.9 $÷$ 26

So, dividing 133.9 $÷$ 26 by standard method, we get:


The quotient is 5.15.

So, the car ran for 5.15 days.
