It takes 10 workers 5 days to complete a road repair when working 2 hours a day.
So, this becomes : man hours required to finish the work.
Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d
So, total man hours =
Now, or
Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.
It will take 10 days for 2 people working 5 hours a day to finish the road repair.
Further Explanation:
From the question;
10 workers can finish road repair in 5 days working 2 hours a day
We need to find;
The number of days required to complete the road repair by 2 workers working 5 hours a day.
Assuming the number of days required to complete the work is x
Number of working hours of 10 people is 10 hours ( 2 hours a day for 5 days)
Number of working hours of 2 people is 5x hours (5 hours a day for x days)
Note that; the number of workers or people is inversely related to the number of working hours.
Therefore;
Product of number of people and working hours or work done is a constant
Thus;
10 × 10 = 2 × 5x
100 = 10 x
x = 10
Therefore;
2 workers working 5 hours a day will require 10 days to complete the road repair.

You are looking for how many miles the car went in 1 hour. You know it went 500 miles in 6.7 hours. To find how many it went in 1 hour simply Divide 500 miles by 6.7 hours.
500 miles/6.7 hours = ____ miles in 1 hour
Final answer:
The average speed of the winning car in the 1911 Indianapolis 500 race was approximately 74.63 mph. This was calculated by dividing the total distance covered (500 miles) by the total time taken (6.7 hours).
Explanation:
The subject of this question is Mathematics, specifically dealing with the calculation of average speed. The average speed is calculated as the total distance traveled divided by the total time taken. From the question, we know that the car covered a distance of 500 miles in 6.7 hours. Therefore, the average speed can be calculated as follows:
- Dividing the total distance covered, 500 miles, by the total time taken, 6.7 hours.
- Perform the division: 500 ÷ 6.7 = 74.63 mph.
The winning car's average speed in miles per hour, rounded to the nearest hundredth, is 74.63 mph.
