Question

Q2. Lamp posts are to be placed along a road. The distance between every two

lamp posts is 10m. How long is the road if a total of 16 lamp posts are to be

placed along the road, including both ends?​

Answer 1

There are 6 lamp posts

Distance between 2 lamp posts = 30 meters

So, total distance between first and sixth lamp post = 5 \times 305×30

= 150150

So, Total distance = 150 m

1 m = 0.001 km

So, 150 m = 0.001 \times 1500.001 ×150

150 m =0.15 km

So, Distance = 0.15 km

Speed = 45 km/hr

Time = \frac{Distance}{Speed}Time=

Speed

Distance

Time = \frac{0.15}{45}Time=

45

0.15

Time =0.00333Time=0.00333

So, it will take 0.00333 hrs to cover the distance
