Question

Which is an expression to find the speed in m/s?
d = 100 m, t = 20 s

Answer 1

It's asking you for a way to write those variables so that you get\[\frac{ meters }{ seconds }\]so, since you have\[d=100meters\]\[t=20seconds\]what should you do to get an answer that has the "meter" units on top, divided by the "second" units

Answer 2

A. 100 - 20
B. 100 + 20
C. 100/20
D. 100 x 20

Answer 3

What ur saying is D

Answer 4

\[ \Large
Speed = \frac{Distance}{Time} = \frac{d}{t} ~m/s
\]

Answer 5

is it D?
