Help middle accel math

OpenStudy (danjs):

remember the formula from last prob distance = rate x time

OpenStudy (danjs):

d=r*t 38 = 2*t

KjSaif (kjsaif):

so 2 * 19 = 38

OpenStudy (danjs):

yeah, divide both sides of the thing by 2 38 = 2*t

OpenStudy (danjs):

38/2 = (2/2)*t t = 38/2

KjSaif (kjsaif):

19 and 1

OpenStudy (danjs):

right, but the answer leaves it as the fraction

KjSaif (kjsaif):

could the answer be 38/2

KjSaif (kjsaif):

which means 38 divided by 2 which gets 19

KjSaif (kjsaif):

@DanJS you there?

OpenStudy (danjs):

yes , right d=r*t given any rate and distance, you can figure out the time required divide by rate r both sides t = d/r they left it as a fraction in the answer

KjSaif (kjsaif):

Thanks!
