Answer :
To keep the same ratio of practice time, Chris should practice the guitar for a total of 59.5 hours over the next seven weeks.
Chris currently spends 17 hours practicing the guitar over a two-week period. To find out how many hours he should practice over the next seven weeks while keeping his practice time proportional, we need to calculate the total number of hours based on the ratio of his current practice schedule.
Since there are seven weeks in the period we are considering, which is equivalent to three and a half two-week periods (since 7 weeks / 2 weeks per period = 3.5 periods), we can multiply Chris's two-week practice time by 3.5 to maintain the same ratio of practice time.
17 hours (per two weeks)
x 3.5 (two-week periods in seven weeks)
= 59.5 hours (over the next seven weeks).
So, Chris should practice for a total of 59.5 hours over seven weeks to keep his practice time proportional to the current schedule.
