Ok, here we have a multiplication and unit conversion, so first we carry out the multiplication and then we convert:
If you run 14 kilometers each week, in five weeks you will have run a total of:
14
x 5
------
70 Kilometers
But if we look at it, no option says 70 kilometers, then it is necessary to pass it to meters:
1 kilometer is equal to 1000m
So 70 kilometers are equal to how many meters?
70
x1000
----------
70000 meters
So, finally we get that the correct option is option D
