# A man working 8 hours a day takes 5 days to complete a project. How many hours a day must he work to complete it in 4 days?

Hint:

**Hint:**

When two quantities of different units are compared and expressed as a ratio, it is known as Rate. For example, a car travels at a speed of 100 kilometres per hour, then it means in one hour it covers 100 kilometres.

## The correct answer is: 10 hours

### It is given that a man is working 8 hours a day and takes 5 days to complete a project.

So, the total number of working hours to complete the project = 8 × 5 = 40 hours

Now, we are asked to determine the number of hours the man must work to complete the project in 4 days.

Number of hours needed per day = = hours

Final Answer:

Hence, the man must for 10 hours a day to complete the project in 4 days.
