Answer:
93.33 minutes
Explanation:
The total time to repair the road is the product of the area of the road and the time it takes to repair one square foot.
Total time = Area of road × Time per square foot
In this case: we have
Area of road = 18.3 square feet
Time per square foot = 5.1 minutes/square foot
Substitute the given value:
Total time = 18.3 square feet × 5.1 minutes/square foot
= 93.33 minutes ( in 2 d.p)
Therefore, it will take 93.33 minutes to repair the section of road.
