Two friends start from the same point. Priya's distance-time line passes through (0,0) and (2, 20); Nisha's passes through (0,0) and (4, 20). How far (in km) has Priya travelled at the moment she is exactly 10 km ahead of Nisha?

Question

Accepted Answer

20. Priya 10 km/h, Nisha 5 km/h, gap grows 5 km/h. Gap = 10 km at t = 2 h. Priya's distance then = 10 x 2 = 20 km.

Two friends start from the same point. Priya's distance-time line passes through (0,0) and (2, 20); Nisha's passes through (0,0) and (4, 20).
How far (in km) has Priya travelled at the moment she is exactly 10 km ahead of Nisha?
