i need this by 10/03/2019

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 =

                                                         = 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 =

                                                                = 30 hours

It would take 30 hours to accumulate 1020 snowballs.
