Ursula and Andre competed against each other in a swimming race.Ursula swam at a rate of 60 meters per minute and Andre swam at a rate of 48 meters per minute. Ursula gave Andre a 1-minute head start.
How many minutes after the race started was Ursula 30 meters behind Andre?
+36915 Ursala Andre(ss) .... I wonder if that was a joke?
Anyway . Andre(ss) has a 1 minute head start = 48 meters ahead
Ursala swims 60-48 = 12 meters/min faster than Andre(ss)
Ursala will close that 48 -30 = 18 meters in 18 m / 12 m/s = 1 1/2 minutes to be 30 m behind Andre(ss)
