Mark ran a mile in 7 1/2 minutes. His brother ran a mile in 6 1/6 minutes. How much more time does Mark take to run the mile?

1 1/3 more minutes

Step-by-step explanation:

Lets first convert both times to improper fractions

7 1/2 -> 15/2 (Mark's Time)

6 1/6 -> 37/6 (Mark's Brother's Time)

Now we need common denominators

15/2 = 45/6

Now times to subtract Mark's time - Mark's Brother's Time = More Time

45/6 - 37/6 = 8/6 or 1 2/6 = 1 1/3

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
