You don't take the bus, it probably is 45mins. You are not including time walking to/from the bus stop at both ends. Time spent waiting for the bus- this is probably the biggest one. Time for people getting on and off at bus stops and paying- in some places, for example in London, there are stops every couple of hundred meters on the route, it is kind of ridiculous.

Having them close together is a massive help to people with mobility issue, bags, and /or small children. TFL policy is to reduce journey times by keeping stops less than five minutes’ from homes, and closer in town centres. The buses also won’t normally stop unless there is someone boarding or alighting.
