Answer 3

hmm how many feet are there in 1 mile?

Answer 4

okok it is 1760

Answer 5

hurry plz

Answer 6

ok, so yes, there are 5280 feet per mile
3 yards per feet, thus
5280/3 = 1760

so we know there are 1760 yards per mile
we also know that there are 60 minutes in 1 hr \(\bf \cfrac{60min}{1hr}\)
and there are 60secs in 1 minute \(\bf \cfrac{60sec}{min}\)

so charlie runs 3yards in 1 sec, that is \(\bf \cfrac{3yd}{1sec}\)

so we can say that
\(\bf \cfrac{3\cancel{yd}}{1\cancel{sec}} \times \cfrac{60\cancel{min}}{1hr} \times \cfrac{60\cancel{sec}}{\cancel{min}} \times \cfrac{1mile}{1760\cancel{yd}}\)

Answer 7

so thats the answer right

Answer 8

that's how you'd convert it, by using the relative units

Answer 9

ok wait about one minute tell i write it down ok

Answer 10

ok wats next

Answer 11

that's all you need to get it :)

Answer 12

ok well wats the answer than

Answer 13

you get it from that unit conversion

Answer 14

well wat do i do there thats wat im meaning

Answer 15

you multiply the fractions, \(\bf \cfrac{3yd}{1sec} \times \cfrac{60min}{1hr} \times \cfrac{60sec}{min} \times \cfrac{1mile}{1760yd}\)

what do you get?

Answer 16

ok wat 1 minute

Answer 17

so its 10800 over 1760 right?

Answer 18

is it

Answer 19

Answer 21

now tell me the truth plz

Answer 22

come on plz hurry

Answer 23

type faster yo

Answer 24

heheh, well, it's so, yes \(\bf \bf \cfrac{3\cancel{yd}}{1\cancel{sec}} \times \cfrac{60\cancel{min}}{1hr} \times \cfrac{60\cancel{sec}}{\cancel{min}} \times \cfrac{1mile}{1760\cancel{yd}} = \cfrac{10800mi}{1760hr}\)

Answer 25

oh ok well thats a no wonder im a straight a studenet
and do we simpify that yes or no

Answer 26

well, yes, you'd need to

Answer 27

ok wat grade r u in

Answer 28

well, keep in mind that we "help", at least I do, we do not give flat answers, so the meaning of "help" is to help you understand how to do the process

so the process is to use the relevant units and cancel out accordingly
