Answer 1

Answer:

472 buses call at the stop between 4:20 and 4:50

total time =30

6 mins in 30 mins are =5

8 mins in 30 mins are =4

15 mins in 30 mins are =2

there are 42 buses in every 5 mins so there are 210 buses in 30 mins

there are 43 buses in every 4 mins so there are 172 buses in 30 mins

there are 45 buses in every 2 mins so there are 90 buses in 30 mins
