Answer:
It would take 4 weeks
Step-by-step explanation:
We can solve this problem most easily by forming it into an equation. We could represent weeks as w.
Since you train 5 more minutes every week, we could represent that as 5w, showing that you work 5 minutes times the number of weeks you worked out.
The constant would be adding 10, since you started out working 10 minutes a day. Now lets just write the equation!
10+5w=30
All we have to do is solve.
Subtract 10 on both sides to cancel out the positive 10.
5w=20
Now just divide both sides by 5 to isolate the w.
w=4
It would take him 4 weeks
Hope this helps!
