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?

The answer is 48 minutes.

Step-by-step explanation:

Let the speed of Max on hoverboard be = x

Then the speed of Victoria on hoverboard will be = 3x

Now its given that the speed of Victoria on foot is 1/3 of the speed of Max on hoverboard, this is = x/3

Formula of speed =

Let the time taken by both to complete the race be t minutes.

Hence, distance covered by Victoria in 12 minutes + distance covered by Victoria on foot = distance covered by Max on hoverboard. Now in equation form this becomes:

Simplifying this we get,

This gives t=48

Hence, t =  48 minutes.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
