Robot P starts from a line and moves at a constant speed of 0.40 m/s. Robot Q starts from the same line 5.0 s later and moves in the same direction at a constant speed of 0.60 m/s.
How far from the line does Q first catch P?
2.0 m2.0\ \mathrm{m}2.0 m
3.0 m3.0\ \mathrm{m}3.0 m
6.0 m6.0\ \mathrm{m}6.0 m
4.0 m4.0\ \mathrm{m}4.0 m
