Ask M50 about travel time between particular junctions. For example: "Alexa, ask M50 for the time between junction 5 and junction 15". Possible junction numbers are from 3 to 17. If the first number is smaller, the direction is southbound. If the first number is bigger, the direction is northbound. In the example above, the direction is southbound.
