Relation between Time, Speed and Distance
Distance covered, time and speed are related by
Relative Speed
(i) If two bodies are moving in the same direction at x km/h
and y km/h, where (x > y), then their relative speed is given by (x – y) km/h.
(ii) If two bodies are moving in opposite direction at x km/h and y km/h, then
their relative speed is given by (x + y) km/h.
