Let's say Rickey took t minutes 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

Together, Rickey and Prejean took t+3/4t = 70

They took 1 3/4 t hours=70 to finish the race

This is 7/4t=70

t=70*4/7

The time that Rickey took to finish the race is t= <<40=40>>40 minutes
