Multiple 16 by 1 and then divide by 8 which makes 2.
Multiply 36 by 1 and then divide by 9 which makes 4.
10:30 because an hour before 11:20 is 10:20, but it was only 50 minutes, so add 10 minutes to 10:20 , and there you have it, 10:30.
We know that speed (rate) is equal to distance over time.
The current unit of distance is miles, and we want to convert it to feet. The unit of time is hours, and we want seconds. In order to do this, we need to create a conversion factor.
Since

and

, we will use these are our conversion factors.
The goal in a dimensional analysis problem like this is for your units to work out. Remember, we want feet per second.
We write

.
You may wonder why in the conversion factor, we chose to put feet over miles and hours over seconds. This is again because we want our units to cancel. If you have one unit the numerator and the same one in the denominator, the units cancel out.
In sum, the answer is
22 ft/s.
Answer:
3600
Step-by-step explanation:
Multiple them
Surface are of a cube = 6a^2
surface area
= 6 (4.5)^2
= 6 x 81 /4
= 243/2
= 121.5
