Question

There are 10 poles placed at equal distance along a road.the distance between every two poles is 15m. What is the distance between the 2nd and 9th poles?

Answer 1

since there are 7 gap b/w 2nd and 9th pole and distance of one gap is 15 m
therefore
required distance = 15×7 m = 105m.

Answer 2

Total distance from pole 1 to pole 10= 15x9= 135

Distance between pole 2 and pole 9 = Total distance--distance from pole 1 to pole 2 (plus)distance from pole 9 to 10

Therefore the distance between 2nd pole and 9th pole = 135-30 =105


Ans:- the distance between pole 2 and pole 9 is 105m
