1.8hour = 1 hour 48 minute
7 X 3 = 21
1h 48 + 21
108 + 21
129
2 hours 9 minutes
Therefore he spent 2 hours and 9 minutes
The difference of the x-coordinate of point A and the x-coordinate of point B is 0
<h3>Coordinates of a point</h3>
The coordinate of a point on an xy-plane is written in the form (x, y). The given figures are circles A and B where the circle A is greater than circle B.
The position of the dots in both sides are positioned at the centre and as such the coordinate point at the centre of both circle will be the origin (0, 0)
According to the question, we are to find the difference of the x-coordinate of point A and the x-coordinate of point B
x-coordinate of pint A = 0
x-coordinate of point B = 0
Take the difference
Difference = 0 - 0
Difference = 0
Hence the difference of the x-coordinate of point A and the x-coordinate of point B is 0
