The quantities include hours and minutes.
The the known and unknown quantities can be used to write an equation and this gives 60 minutes.
<h3>How to explain the information?</h3>
It should be noted that there are two different units of time measurement and these are hours and minutes. In this case, once can either convert the hours given to minutes or vice versa.
Therefore,
2 hours = 120 minutes, and
2.5 hours = 150 minutes.
If x represents the number of potatoes in the bucket, then the time to peel all of the potatoes on the first day will be 1.5x.
The quantity added to the 120 minutes spent making pies is the total elapsed time for the first day's work. The first days time is equal to the second day. This will be:
120 + 1.5x = 150 + x
1.5x - x = 150 - 120
0.5x = 30
x = 30/0.5 = 60
The time taken is 60 minutes.

Find the square numbers and see which ones 54 lies between
1, 4, 9, 16, 25, 36, 49, 64.
It lies between the two square numbers 49 and 64.
But you want the square root.
So find the square root of 49 and 64.
7 and 8.
So the square root of 54 is between 7 and 8.
Hope this helps.
Answer:
The slope is 5/3
Step-by-step explanation:
(12,0)
(0,-20)
Changes in y is -20-0=-20
Changes in x is 0-12=-12
Rise(y) over run(x) = -20/-12
-5/-3
5/3
