Step-by-step explanation:

We can disregard the length of the line from the Library and the House, as Davina does not use that path at all.

We know that 1 unit on the grid represents 1 km. We define the lengths of the route from the graph:

Davina's House to School = 4 units = 4 km

School to Library = 6 units = 6 km

The entire trip Davina takes from House to Library would be 4 km + 6 km = 10 km total.

We also know that Davina takes the same route back from the Library to House. It would be the same exact route and length. Therefore:

2(10 km) = 20 km total

world bank is the correct answer.

the answer is d.index
