when they are both racing on hoverboards, victoria is 3 times as fast as her brother max. when she is on foot, she is 3 times slower than max on his hoverboard. they took off on hoverboards at the same time, but after 12 minutes, victoria’s hoverboard broke and she immediately started to run. if the race was a tie, how long, in minutes, did it last from start to finish?

48 minutes

Step-by-step explanation:

We will use the equation d=rt for this situation, where d is distance, r is the rate of speed and t is the time.

Let r be Max's rate of speed and t be the total time.

With both on hoverboards, Victoria is 3 times as fast as Max; this would be represented as 3r.  She travels at this speed for 12 minutes; this gives us the expression 3r(12).

For the remainder of the race, Victoria is 3 times slower than Max.  This is represented as 1/3r.  We do not know the amount of time she travels this way; we will represent this as 1/3r(t-12), since t is the total time and she has already spent 12 minutes on the hoverboard.

Together the distance on hoverboard and the distance on foot can be represented by d=3r(12)+1/3r(t-12).

This is the same distance that Max travels.  Max's distance is represented using the equation d=rt.  Setting them equal, we have

3r(12)+1/3r(t-12) = rt

Simplifying, we have

36r+1/3r(t)-1/3r(12) = rt

36r + 1/3rt - 12/3r = rt

36r + 1/3rt - 4r = rt

Combining like terms,

32r + 1/3rt = rt

Subtract 1/3rt from each side:

32r + 1/3rt - 1/3rt = rt - 1/3rt

32r = 2/3rt

Divide both sides by r:

32r/r = (2/3rt)/r

32 = 2/3t

Divide both sides by 2/3:

32 ÷ 2/3 = 2/3t ÷ 2/3

32 ÷ 2/3 = t

32/1 × 3/2 = t

96/2 = t

48 = t

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

what are you trying find out?
