  1. 3 hours and 48 minutes = 228 minutes = 8 hours
    90x + 37,5y = 300
    x + y = 3.8
    equations two unknowns
    x = 3
    y = 0.8
    = > 3 hours away on the plains
    = > 0.8 hours to go through the mountains
    0.8 hours = 0,8.60 = 48 minutes

  2. sorry, I typed wrong
    3 hours and 48 minutes = 228 minutes = 3,8 hours
    90x + 37,5y = 300
    x + y = 3.8 [(sorry)]
    equations two unknowns
    x = 3
    y = 0.8
    = > 3 hours away on the plains
