x = 600 min
the whole trip was 10 hours

According to given statement,

The ratio is:

$No.\ of\ Blue\ Paint\ Gallons: No.\ of\ red\ paint\ gallons\\2:4\\Simplifying\\1:2$

Now we will check if the given options can be simplified to 1:2

So,

Option A:

$8:12\\2:3$

Option B:

$8:24\\1:3$

Option C:

$3:5$
