Answer:
The S.I. Unit of speed is metres per second written as m/sec. It is a scalar quantity. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
hope it helps
