Using proportions, it is found that the average daily requirement for these adults is of 2080 calories.
--------------------
- Percentage problems are solved by proportions, using a rule of three.
- 1560 calories is 75% = 0.75 of the calorie requirement for many adults.
- How much is 100% = 1?
The rule of three is:
1560 calories - 0.75
x calories - 1
Applying cross multiplication:
The average daily requirement for these adults is of 2080 calories.

Missing question: Determine the distanced covered by Mary.
Solution:
Mary: 3 mph
Jerry: 4 mph
Jerry starts jogging after Mary had been walking for 15 minutes.
Distance Mary had walked before Jerry starts jogging = Speed * Time = 3*15/60 = 0.75 miles.
Time taken by Jerry to jog for 2 miles = Distance/Speed = 2/4 =1/2 = 0.5 hrs.
Since they stopped at the same time,
Distance Mary walked while Jerry jogged = Speed* Time = 3*0.5 = 1.5 miles
Therefore,
Total distance Mary walked = 0.75+1.5 = 2.25 miles.
