If he spent a total of 1 and three-fourths hours at the gym, which shows the correct equation and solution for x, the number of hours Leo spent at each of the weight machines?
A) 5 x + 2/3 = 1 3/4; Leo spent 13 minutes at each machine.

B) 5 x + 2/3 = 1 3/4; Leo spent 29 minutes at each machine.

C) 2/3 x + 1 3/4 = 5; Leo spent 5 minutes at each machine.

D) 2/3 x + 1 3/4 = 5; Leo spent 10 minutes at each machine.
