Question

Dedi has a rectangular pool in his backyard. The surface area of the pool in 30m^2 and the width is 5m.
There are 4 lights, equally spaced along each of the longer sides of the pool, including a light at each corner.
What is the shortest distance between two lights?

I tried doing 6 as the length (30 as SA / 5 as Width) divided by 4 lights, which = 1.5m but that is not the answer. The answer is 2m. Please help, thanks.

Answer 1

you are correct that there are 4 lights. But that means one at each end, and two in the middle. There are only three spaces between lights, of 2m each.

It's always better to draw a diagram, and this would have been clear.

Answer 2

Yeah, my bad. Thanks a lot!
