How many minutes did Prejean take to finish the race? ** If Prejean's speed in the race was three-quarters that of Rickey, and Rickey took t minutes to finish the race, the time that Prejean took to finish the race is 3/4*t=3/4t
How many minutes did Rickey and Prejean take to finish the race? ** Together, Rickey and Prejean took t+3/4t = 70
How many hours did Rickey and Prejean take to finish the race? ** They took 1 3/4 t hours=70 to finish the race
How many hours did Rickey and Prejean take to finish the race? ** This is 7/4t=70
How many hours did Rickey and Prejean take to finish the race? ** t=70*4/7
How many minutes did Rickey take to finish the race? ** The time that Rickey took to finish the race is t= <<40=40>>40 minutes
