Answer:
1 hour and 6 minutes
Step-by-step explanation:
- A temperature difference of 58-40 = 18°F was obtained in 2 hours
- A temperature difference of 68-40 = 28°F will be obtained in x hours
The next proportion must be satisfied:
18 °F / 28 °F = 2 hours / x hours
x = 2*28/18
x = 3.1 hours in total
Given that she has already waited 2 hours, she must wait 3.1 - 2 = 1.1 extra hours. 1 hour is equivalent to 60 minutes, then 0.1 hours is equivalent to 0.1*60 = 6 minutes.

Answer:
2.25 pounds
Step-by-step explanation:
The diagram showing the weight of bags with grapes is shown in the attached file below.
From the diagram; number of bags of grapes that had a weight of pounds or less is:
pounds = 3
pounds = 4
pounds = 1
Thus; the total is = 3+4+1 = 8
However, The total weight of the grapes in the bag that had a weight of pounds or less is :
=
=
=
=
