Question

A bus cover 250 km from Delhi to Jaipur towards in 5 hours and return back to Delhi by covering same distance in 6 hour find average velocity and average speed​

Answer 1

Answer:

average velocity will be 0 as the body covers no displacement

Average speed = total distance / total time

total distance = 2 ( 250 )

                      = 500 km

total time = 5 +6

                = 11 hr

average speed = 500 / 11

                          = 45.4                            [ approx . ]

hope it helped and please mark as brainliest:)

Answer 2

Answer:

average speed = 45.45 km/hr

average velocity = 0 km/hr .......... because displacement is 0.

Explanation:

Distance from Delhi to Jaipur is 250 km.

Time taken (Delhi to Jaipur) is 5 hours.

$speed = \frac{distance}{time} \\ speed = \frac{250}{5} \\ speed = 50 \: \frac{km}{hr}$

Distance from Jaipur to Delhi is 250 km.

Time taken(Jaipur to Delhi) is 6 hours.

$speed = \frac{distance}{time} \\ speed = \frac{250}{6}$

speed = 41.6 km/hr

$average \: speed = \frac{total \: distance}{total \: time} \\ average \: speed = \frac{250 + 250}{5 + 6} \\ average \: speed = \frac{500}{11}$

average speed = 45.45 km/hr
