The task involves converting between miles and kilometres to calculate the duration of a journey from London to Lincoln. The distance to be covered is 192 kilometres. To determine the travel time, we must consider the speed of the bus, which is given as 55 miles per hour (mph). First, we convert the speed to kilometres per hour (km/h), understanding that 55 miles is approximately equivalent to 89 kilometres. Therefore, the bus's speed is about 89 km/h. To find out how long the journey will take, we divide the total distance by the bus's speed: 192 km divided by 89 km/h, which roughly equals 2.16 hours.

This calculation provides us with an estimated travel time for the bus journey between the two cities. It's important to note that the conversion from miles to kilometres is approximate, and the actual travel time may vary due to factors such as traffic conditions or stops along the route. Nonetheless, the reasoning process demonstrates the practical application of measurement conversions in real-life scenarios, such as planning travel times. In this case, the bus journey from London to Lincoln is expected to take just over two hours.
