1 point A person travels at the rate of 60 miles per hour and covers 300 miles in 5
hours. If he reduces his speed by 10 miles per hour, how long will he take to
cover the same distance ?

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Ibelieve the answer is d. densityhope my answer has you : )

The statement that best describes the object on the right is a bar magnet with its north pole on the left.
