Explanation of Solution
Given information:
Given cities are New York, Dallas, Chicago, Los Angeles, San Franscisco and Washington DC.
It is given that no three cities are collinear.
There are total 6 cities.
Let’s assume that the cities are in a shape of hexagon.
We draw a hexagon and shall connect every city with each other and then count the lines.
Hence we get,
Here we shall observe that there are 15 line connecting each city.
Therefore we can determine that engineer drew 15 lines.
