messages.content: 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
  #### 40
