.02 hr is a little more than a minute


the wildeebest has a .8 mi headstart (.02 hr * 40 mph)


the lion closes the distance at 10 mph (50 mph - 40 mph)


so the lion runs .08 hr to catch the wildeebest (.8 mi / 10 mph)



the lion catches the wildeebest .10 hr after the wildeebest starts running (.02 hr + .08 hr)
___ .10 hr is 6 minutes
