Question
Find the distance with the help of the number line given below.
d (Q, B)
Advertisements
Solution
It is known that the distance between the two points is obtained by subtracting the smaller co-ordinate from the larger co-ordinate.
The co-ordinates of points Q and B are −5 and 2 respectively.
But 2 > −5
∴ d (Q, B) = 2 − (−5)
∴ d (Q, B) = 2 + 5
∴ d (Q, B) = 7
