Question

If the distance between Sydney and Goulburn is 200km find the average speed to complete the journey in 2hr 30mins speed =distance /time

Answer 1

Answer:

the average speed is

$\frac{200}{ \frac{5}{2} } km.h {}^{ - 1} \\ \frac{400}{5} km.h {}^{ - 1} \\ = 80km.h {}^{ - 1}$

Answer 2

Speed = Distance / Time

Here,

Distance = 200 Km/Hr

Time = 2 hr 30 mins means 2.5hrs

Now,

Speed = 200/2.5

Speed = 80 km/hr
