The distance from mile-mark 10 to mile-mark 115 is (115-10) = 105 miles.
Speed = (distance covered) / (time to cover the distance) .
Speed = (105 miles) / (1.75 hours)
Speed = (105/1.75) (mi/hr)
<em>Speed = 60 mph</em> (B)

The speed of the plank relative to the ice is:
Explanation:
Here we can use momentum conservation. Do not forget it is relative to the ice.
(1)
Where:
- m(g) is the mass of the girl
- m(p) is the mass of the plank
- v(g) is the speed of the girl
- v(p) is the speed of the plank
Now, as we have relative velocities, we have:
(2)
v(g/b) is the speed of the girl relative to the plank
Solving the system of equations (1) and (2)
