First we rewrite the expression:
(4x ^ 3) * (2x) ^ - 4
Using properties of exponents we have:
(4x ^ 3) / (2x) ^ 4
Rewriting:
(4x ^ 3) / 16x ^ 4
(x ^ 3) / 4x ^ 4
(1) / (4x)
answer:
An equivalent expression is:

How long dose it take to travel 5km at an average speed of 8 m/s? Give your answers in minutes and seconds

eduard

Answer:

625 seconds and 10 minutes

Step-by-step explanation:

distancs=S=5km=5000m

average speed=v=8m/s

time taken=t=?

as we know that

average speed= $\frac{distance covered}{time taken}$

average speed×time taken=distance covered

here we have to find the time taken

time taken= $\frac{distance covered}{average speed}$

time taken= $\frac{5000m}{8m/s}$

time taken=625seconds

now we convert seconds into minutes

$\frac{625}{60}$

10 minutes
