First you have to remember that to find a percentage you can multiply a number by the percentage's decimal form, for example 40% of 100 would be .40 * 100.
Anyways, 24*.40 =9.6.
To find the percentage however, you must divide 24/40 which equals 0.6, which is equal to the percentage 60%.
To find the third question, you must multiply 24 by 2.5 (0.4 * 2.5 = 1) and you should get 60.
The last question you may have made a typo on, you repeated the first question.
Sal: 25 +5x = 240
Divide 5 from both sides so it would be 5+ x=240/5
Subtract 5 from both sides x=48-5
X= 43
Elena: 15 + 5x=300
Divide 5 from both sides so it would be 3 +x=300/5
Subtract 15 from both sides x=60-3
X=57
So Sal jogged for 43 minutes. While Elena jogged for 57 minutes
