Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

Answers

Answer:

Hi. My explanation is down below. Pls mark as brainliest if its good :)

Step-by-step explanation:

1. Why is 3/3 of 4 equal to 4?

3/3 of 4 = 4 because 3/3 = 1

And 1 of 4 is 4

Also 3/3 of 4 = 3/3*4

since 3/3 = 1

Its the same as 1*4 or 4

2. Why is 2/3 of 4 less than 4

2/3 is less than one, and since the identity property of multiplication says that any number times one is the number itself, a number that is less than one will result to being less than itself.

Proof

3/3 * 4 = 4

2/3*4 = 8/3 = 2  2/3

3. Why is 4/3 of 4 greater than 4?

4/3 is greater than one. 4/3 = 1 1/3

So you will multiply 4 by itself, and then you add another 1/3*4

So the product will be 4 + 1 1/3 = 5 1/3

If my answer is incorrect, pls correct me!
