Answer:
one time.
Step-by-step explanation:
Okay so if he serves 18 customers in 42 minutes divide 18 by 42 and you get the amount of customers he serves per min which is 0.42857413 then multiply that by 120 since 2 hours add up to 120 minutes and you get 51.43
ratio of 6:10, if you divide both numbers by 2 you get a ratio of 3:5
multiply by 2 you get 12:20
multiply by 1.5 you get 9:15
