Question

6. Clark drove of a mile to the store and then of mile from the store to the library. Is the total distance he drove closer to , mile, 3 mile, mile or 1 mile? Explain.

Answer 1

1/2 miles

Step-by-step explanation

to find the total distance, we need to add the distance, so

remember how to add fraction numbers:

`(a)/(b)+(c)/(d)=(ad+bc)/(bd)`

then

Step 1

add the distances

`\begin{gathered} total\text{ distance=}(1)/(5)\text{miles}+(1)/(4)\text{miles} \\ total\text{ distance=(}(1)/(5)+(1)/(4))\text{miles} \\ total\text{ distance=(}(4+5)/(20))\text{miles} \\ \text{total distance=}(9)/(20)\text{miles} \\ \text{total distance=}(9)/(20)=0.45\text{ miles} \\ \text{rounded} \\ \text{total distance=0.5 miles} \\ \text{and } \\ 0.5=(1)/(2)\text{ miles} \\ \end{gathered}`

so, the answer is

`(1)/(2)mile`
