Answer:
<h2>621.207km</h2>
Step-by-step explanation:
We are expected to convert from miles to kilometer
first day 85 miles =136.794km
Second day 125 mile=201.168km
third day 176 miles =283.245km
Total distance covered is 
136.794km+201.168km+283.245km=621.207km
Therefore the total distance in kilometer is 621.207km
 
        
             
        
        
        
Answer:
The cafeteria provides three meals per day.
<u>Reason 1</u>
Yes, they vary directly  
As number of days increases ,Total number of meals i.e 
1st day ⇒ 3
2nd day⇒6
3 rd day⇒9
4th day⇒12
......................
.........................
increases. 
Total number of Meals = k×Number of days
But there is another possibility also
<u>Reason 2</u>
1 st day ⇒ 3
2nd day ⇒3
3rd day⇒ 3
.....................
.....................
As you can see from the above expression On each day number of meals is  
constant.
So we can say that , 
On each Day=Constant amount of meal=3
So, there is no Proportionality between Days and Meal. 
 
        
             
        
        
        
Answer:


Step-by-step explanation:
Given

Solving (a): Equation when it hits the ground.
This means that 
So, we have:


Solving (b): The value of t in (a)

Using quadratic formula, we have:

This gives:




Split



Time can't be negative; So:
