How many weeks will Sanjay need to ride his bike to work in order to ride 150 kilometers?
A. 4 weeks
B. 7.5 weeks
C. 10 weeks
D. 20 weeks

Answer 1

The answer would be 4 weeks

Answer 2

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.
