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)

Answer:
Explanation:
Let the velocity of projection be V .
component of velocity in vertically downward direction = v cos 44.1
component of velocity in horizontal direction = v sin 44.1
s = ut + 1/2 gt²
611 = v cos 44.1 x 5.4 + 1/2 x 9.8 x 5.4²
= 611 = 3.88 v + 142.88
v = 120.65 m /s
b )
horizontal component of velocity of projectile = v sin 44 .1 = 120.65 sin44.1
= 83.96 m /s
horizontal displacement = 83.96 x 5.4 = 453.38 m
c ) horizontal component will remain unchanged so horizontal component
= v sin 44 .1 = 120.65 sin44.1
= 83.96 m /s
d ) velocity of projectile just before striking the ground
v = u + gt
= v cos 44.1 + 9.8 x 5.4
= 120.65 xcos 44.1 + 9.8 x 5.4
= 86.79 + 52.92
= 139.71 m /s
