A bus travels, a distance of 20 km from Chennai central to airport in 45 minutes. What is the average speed?

Answer»

Given:

Distance = 20 km = 20,000 m

Time = 45 min = 2700 s

Formula:

Average speed =\(\frac{Total\,Distance}{Total\,Time\,taken}\)

Average speed = \(\frac{20 km}{45 min}\) = \(\frac{20,000 m}{2700s}\) =

= \(\frac{200m}{27s}\)= 7.4 ms
