A map of an airport is laid out in a coordinate plane. An aeroplane starts at a gate at (0, 0.1). To reach a runway, the plane travels West to (-0.4, 0.1), then south to ( -0.4, -0.8), and then west to ( -0.8, -0.8). What is the total distance to plane travels?

Two trains leave a station on different tracks. the tracks make an angle of 130°, with the station as a vertex. the first train travels 100 km and makes its first stop at point a, while the second train travels 200 km and makes it first stop at point b. how far apart are the trains when both are at their first stop? round the answer to the nearest integer. a) 65 km b) 139 km c) 224 km d) 275 km
