Answer:
The equation for the distance Jane's trainer bikes is
.
Step-by-step explanation:
We have attached diagram for your reference.
Given:
Distance traveled on bike towards south = 16 miles
Distance she ran towards west = 12 miles
We need to find distance Jane's trainer bikes.
Solution:
Let the distance Jane's trainer bike be 'x'.
Now we will assume it to be right angled triangle.
So by Pythagoras theorem which states that;
"Square of the third side is equal to the sum of square of the other two sides."
framing in equation form we get;

Hence the equation for the distance Jane's trainer bikes is
.
On solving we get;

Hence Jane's trainer bikes a distance of 20 miles.
