Question

b. If a standard, tandem axle dump truck can haul 15 tons of ore and the mine is one dayaway from the manufacturing site, how many dump trucks are needed each day?

Answer 1

7 dump trucks

Explanations:

According to the given information, we are told that the total amount of Iron(III) oxide transported every day for operation is 88,915kg.

We are to find the number of dump trucks needed to transport 88,915kg of the ore if a dump truck can only carry 15 tons of the ore.

Convert 15 tons to kilogram

15 tons = 13607.8kg

Calculate the number of trucks required

`\text{Number of trucks required = }\frac{Total\text{ amount transported}}{Amount\text{ transported per truck}}`

Substitute the given parameters;

`\begin{gathered} \text{Number of trucks required}=\frac{88,915\cancel{kg}}{13607.8\cancel{kg}} \\ \text{Number of trucks required}=6.53 \\ \text{Number of trucks required}\approx7\text{trucks} \end{gathered}`

Hence about 7 dump trucks are needed each day to transport 88,915kg of Iron(III) oxide
