Step-by-step explanation:
(12,400{total money} - (12,400{total money} x (1/4) {Mary's cut})) / 5{number of children splitting the remains}

The average speed will be 140 km per hour.
Distance = 350km
Time = 150 minutes = 150/60 = 2.5 hours.
Average speed = Distance / Time
Average speed = 350/2.5
Average speed = 140 km/hr
