Question

What is the speed of a bobsled whose distance-time graph indicates that it traveled 110m in 27s?

Answer 1

The average speed is calculated by the formula: 

$Av.Speed= \displaystyle{ \frac{Distance}{Time}$, 


the distance covered is 110 m, in time = 27s, so using the above formula:

$Av.Speed= \displaystyle{ \frac{Distance}{Time}= \frac{110 \ m}{27\ s}= 4.07 \ m/s$


Answer: 4.07 m/s
