Answer:

4 weeks

Explanation:

Well since he rides his bike 15 kilometers every two period, we can assume that he rides his bike 7.5 kilometers a day. So:


150=7.5x

Where x is the number of days he rides his bike.


(150)/(7.5)=(7.5x)/(7.5)


20=x

So it will take him 20 days to ride his bike 150 kilometers.

Now all we have to do is divide the 20 days by 5 to show how many weeks it took:


(20)/(5)=4

It took him 4 weeks.
