It takes Ricky, traveling at 24 mph, 45 minutes longer to go a certain distance than it takes Maria traveling at 51 mph, Find the distance traveled.

85 mi

Step-by-step explanation:

Let d = the distance in miles traveled

Let M = the time in hours for Maria to travel d miles

time in hours for Ricky to travel d miles

(Note that hrs = 45 min)

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

Maria's equation:

d = 51m

Ricky's equation:

d = 24 ·

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

Substitution:

51m = 24 ·

51m = 24m + 45

6m = 10

m =

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

d = 51m

d = 51 ·

d = 85

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

The distance traveled is 85 mi

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.
