  2. S*T=D
    55/60*a=x
    40*60*b=x+20
    a+b=100
    thus, 60x/55+(x+20)/240=100
    x=91.24
    Total D=x+x+20=202.5miles.

  3. t1 + t2 = 100 minutes = 100/60 hours
    t1 = x/55
    t2 = (x+20)/40

    x/55 + (x+20)/40 = 100/60
    x = 1540/57

    Thus, Total distance = x + (x+20) = 4220/57 miles = 74 2/57 miles
