Observe the given distance-time graph of an object (a straight line rising from 0 metres at 0 seconds to 50 metres at 10 seconds) and choose the correct statement.
Explanation
Explanation
The graph is a straight line through the origin, rising steadily from 0 to 50 metres over 10 seconds, so speed = distance/time = 50/10 = 5 m/s, a constant speed (not acceleration).
PRO TIP
Re-check your working by substituting the answer back into the original question.
