Three students are arguing over who can run the fastest. student a says that she can run 2/3 mile in six minutes. student b says that he can run 1/2 mile in four minutes. student c says that he can run 4/5 mile in eight minutes. type your answer as a number, and if necessary, use / for the fraction bar. fractions should be expressed in lowest terms. what fraction of a mile can student a, b and c run in one minute? hep asap honeuu boo boo

Student-A:

mile/min

Student-B:

mile/min

Student-C:

mile/min

Step-by-step explanation:

Student-A:

she can run 2/3 mile in six minutes

so,

total distance is miles

total time =6 min

we can use formula

speed=(total distance)/(total time)

mile/min

Student-B:

she can run 1/2 mile in 4 minutes

so,

total distance is miles

total time =4 min

we can use formula

speed=(total distance)/(total time)

mile/min

Student-C:

she can run 4/5 mile in 8 minutes

so,

total distance is miles

total time =8 min

we can use formula

speed=(total distance)/(total time)

mile/min

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

step-by-step explanation:

the answer is 128
