Speed= Distance/Time
Given that Distance=50 meters
therefore Total Distance Covered=50*2=100 meters
also given that Time taken = 5 minutes
therefore Total Time taken = 5*2=10 minutes
therefore
Speed=100/10
=>10 meters per minute
Speed in kilometres per hour
=>10*60=600 meters per hour
=>0.6 km per hour
