There are three bus services that run from the bus stop at the end of my street and go to the city centre. As they all take different routes, they take different lengths of time. The quickest bus takes 25 minutes, while the others take 35 and 55 minutes. All of the bus services leave every 30 minutes and I am able to catch a bus from the end of my street every 10 minutes starting from 8am, but I cannot remember in which order the buses arrive. I need to meet a friend at 10.50 in the city centre, What is the latest time I could arrive at the bus stop and still be sure to get to the city centre in time? A 09:50 B 10:00 C 10:10 D 10:20
