Best ResponseYou've already chosen the best response.0just follow these steps. 5/12=7/x x there is the time for a set do the cross multiplication. 5x=84 x=16.8, but there are 20 sets so, all we have to do is multiply this by 20. x=16.8(20)= 336 minutes 336 minutes is equal to 5 hours and 36 minutes.
