Question

What is the value of time, t, for the given values of distance, d, and rate, r?

d = 425 m, r = 50 m/s









A.
8.5 m







B.
8.5 s







C.
21,250 m







D.
21,250 s

Answer 1

You know the equation relating distance, rate and time?
d = r * t

Answer 2

c

Answer 3

I'm trying to figure it out still don't get it

Answer 4

We want to substitute in our values of d and r:
d = 425, r = 50
425 = 50 * t
and solve for the variable t.

Answer 5

I got it and I got c

Answer 6

c? We are looking for time, and the unit on (c) is meters...

Answer 7

i said c the 2nd comment

Answer 8

what is s?

Answer 9

We divide both sides by 50:
\( 425 = 50 * t \)
\( \dfrac{425}{50} = t \) We calculate this.
The unit of time has to be seconds, or we can note that we divided distance (m) by rate (m/s). Meters / (Meters / Second) = Seconds * Meter/Meter = Seconds

Answer 10

Its b

Answer 11

Access denied u r right.

Answer 12

so what the answer

Answer 13

Did you understand what we posted here? Perform the operation: 425 / 50. The unit is time, so it has to be in seconds (s) rather than meters (m).

Answer 14

no I get it
