Answer:
Step-by-step explanation:
Given:
Number of miles is represented by 
and number of hours is represented by 
.
The equation to show the relationship between and is 
Now, for 
Plug in the above equation and solve for 
. This gives,
Hence, the equation is 
.
Now, if the line passes through 
, then 
.
So, 
Therefore, the value of is 270 miles.
Speed of student A is 180 ft/min
Speed of student B is 120 ft/min
Relative speed=(120+180)=300 ft/min
Distance between them is 2420 ft
Time taken for them to meet will be:
time=distance/speed
=(2420-20)/300
=8 min

Step-by-step explanation:
Answer:
For this case, the first thing we must do is define variables:
x: number of hammers
y: number of wrenches
We write the system of inequations:
10x + 6y <= 120
x + y> = 14
