Spiro travels 140km per week travelling to and from work. If Spiro works 5 days per week. What distance is his work from home?
Ber [7]

Answer:

14 km

Step-by-step explanation:

<u>1) look at the information you are given:</u>

140 km total (<em>to and from work</em>)

Note that this number includes both the distance to work and the distance from work.

He works 5 days a week.

<u>2)Figure out the distance he travels within one day</u>

This means that you should take the 140 km and divide it by 5 in order to find out the amount of km he travels each day.

<h2>140 km / 5 days = 28 km</h2>

28 km is the amount of KM he travels each DAY.

<u>3) Figure out the distance from work to home </u>

From this point, it is important to note the question is asking for <u>the distance his work is from home.</u>

Each day, he must travel 2 times: he must go to work and go from work to home, which are both the same distance.

This means that in order to get only the distance from work to home, you must divide by 2.

<h2>28 km / 2 = 14 km</h2>
