Hello! :)

Answer 3

Hi could you help me solve this problem?

Answer 4

This is very simple; we are trying to find how many hours she rode in total today, so our formula is :
Miles / miles per hour

For example, if she rode 25 miles in the day, going at a constant speed of 12 we would divide 25 by 12 we would find out that she rode 2.1 hours. (2.08, but I estimated)

Answer 5

That means what you need to do is divide the miles by the mph earlier that day, and then add it up with the later of the day.

Miles / mph + Miles / mph = hours

Answer 6

Do you get it? :)

Answer 7

So i would divide 24 by?

Answer 8

How many mph was she going when she rode 24? :)

Answer 9

time = distance / speed

Answer 10

15

Answer 11

So, so far we know that our equation is
Miles / mph + 24 / 15 = hours

Answer 12

What is the other Miles / mph ?

Answer 13

12

Answer 14

Miles / 12
What is the "miles" ?

Answer 15

t = d/t

t = 18/12 + 24/15

Answer 16

oops...t = d/s

Answer 17

Lol
Times = distance / time :P

Answer 18

lol...way too many formulas in math to remember

Answer 19

I never payed attention to formulas as a kid o.o
I always just did it logically in my head.... I would always studder when teacher asked to write out my work because I did it all mentally lol.

Answer 20

well...as long as you got the right answer...I don't think it really matters

Answer 21

Nope, they always yelled at me. o.o
