Answer :
Final answer:
Martin will practice 42.5 hours in 5 weeks. Therefore, the correct option is 1
Explanation:
To find the number of hours Martin will practice in 5 weeks, we need to set up a proportion. We know that he practices 17 hours in a 2-week period, so let's set up the proportion:
2 weeks : 17 hours = 5 weeks : x hours
Using cross-multiplication, we can solve for x:
2x = 5 * 17
2x = 85
x = 85 / 2
x = 42.5
Therefore, Martin will practice 42.5 hours in 5 weeks.
