All pillars of street light was installed in a straight line at a distance of 50 meter(m) interval. What will be the distance between first and ninth pillar ?
Given:
Distance between two adjacent pillars = 50 m
Number of pillars = 9
Formula Used:
Total Distance = (Number of pillars - 1) × Distance between adjacent pillars
Solution:
The number of intervals between the 9 pillars is calculated by subtracting 1 from the total number of pillars.
Intervals = 9 - 1 = 8
Total distance = 8 × 50 = 400 m
Final Answer
So the correct answer is (d)
