A dump truck can haul 16 loads of dirt in 4 hours. How long will the dump truck spend hauling 25 loads?
16/4 = 4 per hour
24/4 = 6.25 hours
6.25 is the correct answer ps.i am from the year 2017 five years from 2012 ;3
To find out how long the dump truck will spend hauling 25 loads, we can set up a proportion using the given information.
Let's assume "x" represents the time it takes to haul 25 loads.
We know that the dump truck can haul 16 loads in 4 hours, which can be expressed as the ratio: 16 loads / 4 hours.
To set up the proportion, we can use the fact that the dump truck hauls 25 loads in "x" hours: 25 loads / x hours.
Setting up the proportion, we have:
16 loads / 4 hours = 25 loads / x hours
To solve for "x," we can cross-multiply:
16 loads * x hours = 25 loads * 4 hours
16x = 100
To isolate "x," we can divide both sides of the equation by 16:
x = 100 / 16
x ≈ 6.25
Therefore, the dump truck will spend approximately 6.25 hours hauling 25 loads.
