So Parvez drives 3 times the hours that Misty does.
Let's use the "times" as "x."
So Parvez = 3x, and Misty = x. Together, they drove a total of 12 hours.
So to make that an equation, we would have:
3x + x = 12
Combine like terms:
4x = 12
Divide both sides by 4:
x = 3
So Misty drove a total of 3 hours. Now to find the number of hours Parvez drove, we can either subtract 12 by 3 or solve 3x, which is 3(3), both gives you 9. So Parvez drove 9 hours.
