The total displacement of the person walking from point A to point B is 300 yards.
As shown in the figure we can conclude that the required method to calculate the total displacement is the Pythagoras theorem.
<h3>Pythagoras theorem in brief :</h3>
According to the Pythagorean Theorem, the square that represents the hypotenuse, or side of a right triangle that faces the right angle, is equal to the total of the squares on the triangle's legs.(or, in popular algebraic notation,
).
<h3>Calculation: </h3>
Let,
a = 500
b= 300
Hence by using Pythagoras' theorem
Total displacement of the person =
=
= 
Thus the total displacement of the person from starting point is 300 yards.

Time should not be messed with
for bad things could happen
so think before you act or you'll regret it
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
