Hi there!
Since the store has an average of 90 seconds to process a sales transaction, this means that it takes, on average, <u>90 seconds per customer</u>.
You want to know how much time will have passed when the last sales transaction is comlete, which is after <u>3 clients</u>.
It takes 90 seconds for 1 customer, so in order to know how much time it takes for 3 customers you have to multiply the time it takes for one customer (90 seconds) by the number of customers in line (3) :
90 seconds × 3 customers = 270 seconds.
To convert 270 seconds into minutes, you need to divide the number of seconds (270) by 60 (because there are 60 seconds in 1 minute):
270 ÷ 60 = 4.5 minutes
Your answer is: a) 4.5 minutes will have passed when the last sales transaction is complete.
There you go! I really hope this helped, if there's anything just let me know! :)
