I think there is a mistake in the question - in any case it is not clear.

44 mins to travel 1 km is probably not correct. - that is LESS than 1 mph

If he is 'halfway' into 20 min ride is that 10 minutes? or is it half the distance?

If he totals 55km in 20mins that is 165 km/h (approx 100mph) 

The figures do not make reasonable sense
