Question

A construction crew has just finished building a road. The road is 10 kilometers long. If the crew worked for 3 3/4 days, how many kilometers of road did they build each day? (Assume they built the same amount each day.) Write your answer as a mixed number in simplest form.

Answer 1

`\begin{gathered} \text{They built;} \\ 2(2)/(3)\text{ km daily} \end{gathered}`

Here, we want to get the number of kilometers of road built each day

We have this as follows;

We can get this by dividing the number of kilometers by the number of days it took to build the road

We have this as;

`\begin{gathered} 10\text{ divided by 3}(3)/(4) \\ \\ =\text{ 10 divided by }(15)/(4) \\ \\ =\text{ 10 }*(4)/(15)\text{ = }(40)/(15)\text{ = }(8)/(3)\text{ = 2}(2)/(3)\text{ days} \end{gathered}`
