Question

What is the speed of a bobsled whose distance-time graph indicates that it traveled 100 m in 25 s?

Answer 1

As per the question, the distance travelled by bobsled [s] = 100 m

The time taken by the bobsled to travel that distance [t] = 25 s

We are asked to calculate the speed of the bobsled.

The speed of the bobsled is calculated as -

                                            $speed\ =\ \frac{distance}{time}$

                                            $v\ =\ \frac{s}{t}$

                                                   $=\frac{100\ m}{25\ s}$

                                                   $=\ 4\ m/s$

Hence, the correct answer to the question is A. 4 m/s.
