Answer:
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
