Answer:
Speed = 450 miles per hour
Explanation:
Given the following data;
Time = 2 hours
Distance = 900 miles
To find the speed of the plane;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting into the formula, we have;
[tex]Speed, S = \frac{900}{2}[/tex]
Speed = 450 miles per hour
Answer: The speed of the plane in miles/ hour is equal to 450miles/ hour.
Explanation:
Speed has the property of magnitude ( size) but no direction. For example, an object moving at a speed of 40m/s has a higher speed that one moving at a speed of 20m/s.
The SPEED of an object is defined as the rate of change of distance moved with time. Thus, if a journey from London to Barcelona is 900miles and takes 2 hours. The speed of the plane is determined using the formula below:
Average speed = distance/ time
Distance = 900miles
Times = 2hours
Therefore speed = 900 ÷2
SPEED = 450miles/hour
Note that speed is measured in meter per second. But according to the instruction given from the question, it was stated that the speed should be calculated in miles per hour. Therefore the answer is 450miles/hour.
