Answer: 40
Step-by-step explanation:
<h2>
Hello!</h2>
The answer is:
The airplane will travel 8800 feet in 10 seconds.
<h2>Why?</h2>
It's a conversion exercise, we need to be careful in order to solve it with no mistakes.
First:
We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:

Second:
We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.
So, solving we have:

Now, calculating how many feet does it travel in 10 seconds, we have:

We have that the airplane will travel 8800 feet in 10 seconds.
Have a nice day!
D=vt
So they will travel downstream and upstream the same distance. Downstream they will travel:
d=(2+18)t1
Upstream they will travel:
u=(18-2)t2
Since d=u we can say:
20t1=16t2
We are told the trip lasts 3 hours so t1+t2=3, t2=3-t1, using this in the equation above we have:
20t1=16(3-t1)
20t1=48-16t1
36t1=48
t1=4/3 hours, and from earlier we saw that d=20t1 so:
d=20*4/3
d=80/3 miles
d=26 2/3 miles.
Answer:
3/4
Step-by-step explanation:
if for 3 potatoes take 1/4 then you just add 3 more potatoes and plus 1/4 to the 1/4 you already have which gives you 2/4 and then add 3 more potatoes to the 6 that you have which equals nine potatoes and 1/4 to the 2/4 you already have which equals 3/4 so 3+3+3= 9 potatoes and 1/4+1/4+1/4 =3/4 hope this helped plz give brainliest
