Answer 2

this looks like a conversion problem

Answer 3

there are two ways that this can be done. So for now, I'll just give you the easier one

Answer 4

Since the unit of kilometers stays the same, you would set this up as a ratio problem

Answer 5

Please do haha
I have 3 months of math to finish by dec 18

Answer 6

wow, that sounds painful

Answer 7

yeah while working 2 jobs a 9-5and a 5:30 -9:30 5 days a week it is

Answer 8

and my only 2 days off are class days D:

Answer 9

Alright. So far, we know that there is a rate of 62k per hour.

so we start off with this:

\(\Large\frac{62 km}{hour}\)

Answer 10

62/2=31

Answer 11

since we know that there are 60 minutes in 1 hour, we multiply this onto the existing fraction.

\(\Large\frac{62~km}{1 ~hour}\times\frac{1 hour}{60 minutes}\)

Answer 12

62*60*1

Answer 13

3720

Answer 14

since the "hour" units are the same, we can cancel these out, which gives us:
\(\Large\frac{62~k}{60~minutes}\)

Answer 15

if we simplify this down you get 31/30.

I'm not sure what you were doing, but the values that you are obtaining are much too high

Answer 16

i cross multiplied

Answer 17

recall that if the car is going at 62 kilometers per hour, the it will be going less per minute, given that the speed stays the same. we want to maintain equivalent values

Answer 18

1.0333333

Answer 19

with these types of problems, and when adding the units, you don't need to cross multiply.

and yes, 1.0333333 is what you should be getting
