of 44 Step 1 of 1
How many scoops will it take a 2-ton crane, which can scoop 2 tons of material at one time, to move 23,000 pounds of dirt? Round to the ten
thousandths place, if necessary.

Answer 1

Using proportions and conversion of units, it is found that 6 scoops are needed.

Each pound has 0.0005 tons, the measure of 23,000 pounds in tons is:

$T = 23000(0.0005) = 11.5$

Now, 11.5 tons are going to be moved. In each scoop, 2 tons are moved. How many scoops are needed to move 11.5 tons?

The proportional relationship is:

1 scoop - 2 tons

x scoops - 11.5 tons

Applying cross multiplication:

$2x = 11.5$

$x = \frac{11.5}{2}$

$x = 5.75$

Rounding up:

6 scoops are needed.
