Curtis traveled a distance of 12 miles in 2 hours from the park to his home. what was his average speed in miles per hour?

12/2= 6 miles/hour
*(miles/hour) & (miles per hour) mean the same thing, by the way

Put the 12 miles in the numerator and the 2 hours in the denominator, divide the 2 hours by 2 (which will be 1) since we want to know the distance travelled in "one" hour. Then divide the 12 by 2 because what you do with the denominator must also be done with the numerator and vice versa.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
