2) 0.59
3) 85
4) 34

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.
