Answer
To find the average speed, first calculate the travel time:
They leave at 04:00 and need to arrive by 09:30, which gives a total travel time of 5 hours 30 minutes, or 5.5 hours.
Next, use the formula for average speed:
ext{Average Speed} = rac{ ext{Distance}}{ ext{Time}} = rac{496.9}{5.5} \\ \\ ext{Average Speed} = 90.34 ext{ km/h (rounded to 90 km/h)}
