The distance a car travels, d, is proportional to a constant rate of speed, r, at different times, t.
which equation shows the relationship between the distance the car travels and the speed of the car?
a. d=rt
b. d=r+t
c. d=r-t
d. d= r/t

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
