Ross walks every morning. he can cover 6 miles in 2 hours. his speed is miles per hour. he can cover more miles in 4 hours than he can in 3 hours.

Yes his speed is 3 miles per hour

Step-by-step explanation: divide by the amout of time in 2 hour and thats how many hours it take to walk that many miles.

We know that speed is defined as the ratio of distance over time.

i.e.

It is given that:

The distance covered by Ross is 6 miles and the time taken by him is: 2 hours.

This means that his speed is:

Also,

Hence, distance covered by him in 4 hours at the same speed is:

and the distance traveled by him in 3 hours is:

Hence, the extra miles he covers in 1 hour is:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
