1.) Sam raked 4 bags of leaves in 22 minutes. If
he continues to work at
the same rate, about
how long will it take
him to rake 7 bags?

38.5 minutes, aka 38 minutes and 30 seconds, round up, unless ur teacher wants the exact time.

38.5 minutes or if rounded up it would be 39 minutes.

Step-by-step explanation:

22 divided by 4 bags would get you 5.5. This means it would take you 5.5 minutes to rake 1 bag. Since, they already raked 4 bags that would be 22 minutes, plus the other 3 bags it would be, 5.5 x 3 = 16.5 minutes. Add it together and you get 22 minutes + 16.5 minutes = 38.5 minutes to rake 7 bags. Hope this helped!
