Well, as you know, there are 60 minutes in 1 hour. So you just have to compare. So; 60 minutes= 1 hour 180 minutes= y hours I represented the unknown with y as you can see. Anyway, you have to cross multiply. So 1 multiplies 180 and 60 multiplies y. So that will be; 60y=180 Divide the both sides by 60. So; 60y/60=180/60 y=3 hours. So the answer is 3 hours. Hope i helped. Have a nice day
