    Since he must not exceed 8 hours driving in a day:

    Let the distance of the picnic be = x km.

    Therefore time for forward journey = x / 60

    Return journey = x / 50

    The total trip should not exceed 8 hours.

    Therefore: x / 60 + x / 50 < = 8. LCM = 300

    Taking LCM and multiplying on both sides:

    5x + 6x < = 8 (300)

    11x < = 2400

    x < = 2400/11

    x < = 218.18

    The picnic spot must be less than or equal to 218.18 km.
