Answer:5280 ft are in a mile
Step-by-step explanation:
1.
Height h = 240 feet
We insert it into formula.

Now we solve this for t:

We have two answers as the rocket will pass this height on it's way up and down.
2.
Height h = 0 feet
We insert it into formula.

Now we solve this for t:

We do not consider solution -1 as the time can not be negative. Our solution is 5s.
3.
Height at bottom of hill h = 0 feet
We insert it into formula.
135 /43 = 3.14
60 * 3.14 = 188.4 minutes
You will have to add your whole then multiply your fraction
Answer:
130
Step-by-step explanation:
Times 40 & 3 to get 120.
Then as 1 is equal to 1/4 and 4 is equal to 4/4 which is a whole.
As 4 = 4/4 or 1 whole.
Count by 4 with your fingers until you get 40. Which is ten.
Then add 120+10 which equals to our answer that is 130.
