Question

d=rt equations

Answer 1

solve for?

Answer 2

there and back solve for time

Answer 3

t=time?

Answer 4

the whole problem is she went to a place at 80 km/h then returned at 60. the trip back took 4 hours how long did the trip there take?

Answer 5

60km/h

Answer 6

okay euler its all you. i can figur this one out though...

Answer 7

since d there and d back are equal.

r1t1=r2t2

80*4 = 60t2

t = 16/3

Answer 8

1 and 2 being subscripts for there and back respectively

Answer 9

um... what is the whole equation im still confused

Answer 10

d = rt

distance = rate * time

rate is distance/time = speed

Answer 11

well yeah but, nevermind

Answer 12

i'd love to help, but i don't understand the question

Answer 13

im usually good at math but drts are hard

Answer 14

\[d=rt\]\[d_{there} = r_{there}*t{there}\]\[d_{back} = r_{back}*t_{back}\]

since the distance there and back is equal:
\[d_{there}=d_{back}\]\[r_{there}*t_{there} = r_{back}*t_{back}\]
plug in values

\[80*4 = 60*t_{back}\]

Answer 15

thanks
