two buses leave at the same time.
one travels west at 40 mph.
the other goes north at 30 mph.
When will they be 400 miles apart?

  • algebra - ,

    (30t)^2 + (40t)^2 = 400^2

  • algebra - ,

    30t+40t=400
    70t=400
    t= 400/70
    =5.71hrs
    After 5.71hrs they will be at 400miles apart.
