By using the following formula we can calculate the distance:
Distance = Speed x time
Speed = 55 m/s
Time = 2 hour 23 minutes = 143 minutes = 8580 seconds
Distance = 55 m/s x 8580 seconds
=471900 meters = 471.9 km
A car travels 471900 meters or 471.9 km if it was on the road for 2 hours and 23 minutes and traveled at an average speed of 55 m/s.
