Question

Look at the formula for finding distance.
d = rt


A. t = d
---
r
B. t = d - r


C. t = r
---
d
D. t = dr


How do you do this?

Answer 1

assume r=velocity

d=rt

Answer 2

standard formula for velocity is \[v=\frac{d}{t}\]
Multiply both sides by 't'
d=vt

Answer 3

I don't understand, sorry. This is very confusing.

Answer 4

which grade you in?

Answer 5

you mean you want to find "t"?

Answer 6

how do you multiply a letter by a letter is what i don't understand -.-

Answer 7

Just divide both sides by "t"

\[d = rt\]

\[\frac{d}{r}=\frac{rt}{r}\]
\[\frac{d}{r}=\frac{\cancel rt}{\cancel r}\]
\[\frac{d}{r}=t\]

Answer 8

I mean divide both sides by "r"

Answer 9

So its A

Answer 10

@michaelJordan you are not multiplying by a letter.they are symbols that is used to represent a variable value.its a number afterall.

Answer 11
