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?

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)
