Answer:
It will take weeks to complete the repair of the stretch of road.
Step-by-step explanation:
Given:
Length of the roads that need repairs =
Length of the road workers can repair in a week =
To find the number of weeks will it take to repair this stretch of road.
Solution:
Unit rate of workers to repair roads = per week.
Total length of the roads to repair =
The number of weeks it will take to repair of road by workers can be given as:
⇒
<em>In order to divide mixed numbers, we convert them first to fractions.</em>
⇒
<em>To divide fractions, we take reciprocal of the divisor and replace division with multiplication:</em>
⇒
⇒
We reconvert the fraction to mixed number.
⇒ weeks
Thus, it will take weeks to complete the repair of the stretch of road.
The median of a data set is the number that is the middle value.
First you have to rearrange the numbers from greatest to least.
If there are any odd numbers then the median is in the center term.
If there is an even number of terms, you add the two middle terms and divide them by 2.
