Explanation:
600 ÷ 60 = 10
1500 ÷ 10 = 150 minutes
I don't know how you should express the answer in:
So it's either 150 minutes or 2 hours and 30 minutes.
(This is kind of like mathematics, not physics)
It makes an echo and it circles around it.
Answer:
speed = 3.95 m/s
Explanation:
area = π x radius^2
area = π x (2.67 x 10^-3)^2
volume flow rate = area x speed
volume / time = area x speed
density = mass / volume
volume = mass / density
<u>mass / (density x time) = area *speed</u>
mass flow rate = mass / time
<u>mass flow rate / density = area x speed</u>
6.55 x 10^-2 / 740 = pi * (2.67 x 10^-3)^2 * speed
speed =8.8514 x 10-5 /2.2396 x 10-5 m/s
speed = 3.95 m/s
