Answer:
3 hours and 20 minutes
Step-by-step explanation:
Jack's rate is 1 puzzle for every 5 hours, so his rate per hour is 1/5 of a puzzle per hour.
We need to find the rate of his brother so here is our equation,
1/5 + 1/x = 1/2
1/2 - 1/5 =1/x
3/10 = 1/x
3/ 3x = 3/10
3x=10
x= 3 and 1/3 hours
3 hours and 20 minutes
