Respuesta :
you can set up a proportion
15 mins / 6 uv = x / 10 uv
Cross multiply
15 x 10 = 150
6 x X = 6x
150 = 6x
divide by 6
x = 25
So, as 25 minutes, the uv is 10
15 mins / 6 uv = x / 10 uv
Cross multiply
15 x 10 = 150
6 x X = 6x
150 = 6x
divide by 6
x = 25
So, as 25 minutes, the uv is 10
First you multiple 15 by 10 and you get 150 and then you Divide 150 by 6 and you get 25. So at a uv rating of 10 it will take you 10 minutes
