Sasha works as a driver for a delivery company.
At the end of each day Sasha works out the mean distance she has driven so far that week.
At the end of 5 days, the mean distance she has driven is 185.5 miles per day.
At the end of 6 days, the mean distance she has driven is 190 miles per day.
Work out how many miles Sasha drove on the sixth day of that week
Answer:
In the first 5 days the total distance driven was 185.5 multiplied by 5 or 927.5
In the first 6 days the total distance driven was 190 multiplied by 6 or 1,140
To find the amount driven on the 6th day subtract the two to find the difference
1,140 – 927.5 = 212.5 miles
