Speed = distance / time
Speed = ? 
Distance = 350km
Time = 5 hours
350km / 5hours = 70
He averages 70km/h
        
             
        
        
        
For first pound it is = $2.41
For next six, = 0.41 * 6 = $2.46
Remaining = 7.99 - (2.41 + 2.46) = 7.99 - 4.87 = 3.12
Now, additional pounds = 3.12 / 0.39 = 8
Total weight = 1 + 6 + 8 = 15
In short, Your Answer would be 15 pounds
Hope this helps!
