Answer:

After 12.2 miles

Step-by-step explanation:

You can check this by graphing y = 0.85+16.75 and y = 0.40 + 22.25 and looking for the solution (the point where they intersect).

You can also use the elimination or substitution method.

A taxicab company charges $2.10 plus $0.80 per mile. Carmen paid a fare of $11.70. Write and solve an equation to find the numbe

Answer:

y=0.8x+2.1

x= 12 miles

Step-by-step explanation:

Using the standard charge of 0.8 per mile and a fixed charge of $2.1. Let x represent the miles covered then the expression for coat at any given mile will be y=0.8x+2.1

Substituting $11.7 for y then we can find the valje of x as 11.7=0.8x+2.1

0.8x=11.7-2.1=9.6

X=9.6/0.8=12 miles

Answer:

See Explanation

Step-by-step explanation:

Given

$T_1 = 2\ hours$ ---------- A to B

$T_2 = 4\ hours$ ---------- B to C

Required

Determine the average speed of Mr. Ali's journey

To do this, we have to calculate the total distance covered.

i.e.

Distance = Town A to B + Town B to C

$Total\ Time = T_1 + T_2$

$Total\ Time = 2 + 4$

$Total\ Time =6$

The distance between the towns are not given. So, I'll make an assumption.

-------------------------------------------------------------------------------------------------------------

Assume:

Town A to B = 5km

Town B to C = 10km

$Total\ Distance = 5km + 10km$

$Total\ Distance = 15km$

-------------------------------------------------------------------------------------------------------------

Average Speed is then calculated as:

$Average\ Speed = \frac{Total\ Distance}{Total\ Time}$

$Average\ Speed = \frac{15}{6}$

$Average\ Speed = 2.5km/hr$
