Question

A bobsled’s distance-time graph indicates that it traveled 100 m in 25 s. What is the bobsled’s speed?

Answer 1

Speed is defined as distance over time. So, since it traveled 100m in 25 sec, the speed was 100 / 25 = 4 m/s.

Answer 2

Its AVERAGE speed for the whole 25s was (100m/25s)= 4 m/s.

It may have been faster or slower than that at different times during the 25s. You'd have to see the graph to know what it was at any particular instant.
