Boulder dash run 6 times every 20 minutes how many times will it run an hour and a half answer

We are given data of a boulder dash run with 6 times every 20 minutes. We are asked to determine how many times will it run an hour and a half. We can set-up an equation to solve this problem.

First,

let y = total number of times 
     x = time duration

So, 

y = 6 times / 20 minutes * x
y = 0.3x times

Now, we can substitute the total time duration from the problem, 1 hour and 30 minutes:

Convert 1 hour to minutes = 60 minutes + 30 minutes, total duration = 90 minutes

Using the equation:

y = 0.3 times per minute * 90 minutes 
y = 27 times

Therefore, in the boulder dash, you need to run 27 times.
