A construction company needs to remove 4 1 6 tons of dirt from a construction site. They can remove 8 9 tons of dirt each hour. What is the total number of hours it will take to remove the dirt

4.84 hours

Step-by-step explanation:

Let the total hours taken to remove all the dirt be x

The construction company wants to remove 416 tons of dirt from the construction site.

They can remove 86 tons of dirts each hour

That’s 86 tons = 1 hour

Total hours it’ll take to remove 416 tons of dirt ?

That’s 416 tons = x hours

Combine the two equations.

86 tons = 1 hour

416 tons = x hour

Cross multiply

X x 86 = 416 x 1

86x = 416

Divide both sides by 86

86x/86 = 416/86

x = 4.84 hours

It’ll take the construction company 4.84 hours to remove the dirt
