Answer:
The answer to your question is ratio = 9/11
Explanation:
Sylvia 3:45
Paul 4:35
Ratio Sylvia / Paul
Process
1.- Convert the time to minutes
Sylvia 1 h --------------- 60 min
3 h --------------- x
x = (3 x 60) / 1
x = 180 min
Total time = 180 + 45 = 225 min
Paul
1 h --------------- 60 min
4 h -------------- x
x = (4 x 60) / 1
x = 240 min
Total time = 240 + 35 = 275 min
2.- Find the ratio Sylvia / Paul
225/275 = 45/55 = 9/11
