Question 41861
Let us suppose that the distance of the office from his starting is 'x' km.
Therefore, when Jason passes the bank he has traveled {{{x/3}}} km.
Also, when he passes the store he has traveled {{{3x/4}}} km.
Then the distance between the bank and the store is {{{3x/4 - x/3=5x/12}}} km.


When Jason passes the bank, time is 6:52 am and when he passes the store the time is 7:02 am.
Therefore, he traveled this {{{5x/12}}} km (distance between bank and store) in 10 minutes.
[Since time from 6:52 to 7:02 is 10 mins.]


Now, Jason travels {{{5x/12}}} km in 10 mins.
So, he travels {{{1}}} km in {{{10/(5x/12)}}} = {{{24/x}}} mins.
or he travels {{{x/2}}} km in {{{(24/x)*(x/2)}}} mins = 12 mins.


So, Jason travels half the distance to his office in 12 mins or in other words is halfway on his walk to office in 12 mins.
