Answer:
A. Speed
Explanation:
Speed is the magnitude of velocity, which is given in the question. Velocity is a vector quantity and therefore has both a magnitude and a direction. Only the former is implied in the question.
So power is equal to work over time and work is force times distance, you do 5 times 3 and get 15 dividing by 2 gives us 7.5 W answer c

Answer
given,
tourist travels = 1500 miles
second plane averages 50 miles per hour faster than the first plane.
x = y + 50
The tourist uses the slower plane for the first 500 and the faster plane for the next 1000 miles.
total flying time = 6.5 hours





on solving equation
y = 86.67 mile/hr
x = 86.67 + 50
x = 136.67 mile/hr
