    Answer:

      55.5 seconds

    Step-by-step explanation:

    The distance between the deer and bear is increasing at the rate of …

      (7 ft/s) +(3 ft/s) = 10 ft/s

    The total distance apart we’re interested in is …

     (185 yd)(3 ft/yd) = 555 ft

    The time required to make a gap that large is …

      time = distance/speed = (555 ft)/(10 ft/s) = 55.5 s

    It will be 55.5 seconds until the animals are 185 yards apart.
