Answer:
30 hours.
Step-by-step explanation:
James is making snowballs to build a fort during winter break.
The number of snowballs he can form in one hour = 50
but in every 15 minutes the number of snowballs melt = 4
There are 60 minutes in one hour = [tex]\frac{60}{15}[/tex]
= 4 time period of 15 minutes
In one hour number of melted snowballs = 4 × 4 = 16
So the remaining snowball in one hour = 50 - 16 = 34 balls
James accumulates 34 balls in one hour.
To accumulate 1020 snowballs, it takes time = [tex]\frac{1020}{34}[/tex]
= 30 hours
It would take 30 hours to accumulate 1020 snowballs.
