Question

Gautam travels 160 kms at 32 kmph and returns at 40 kmph. Then average speed is

Answer 1

36 km/ hr is the average speed of the gautam travels.

Answer 2

Answer:

The average speed = 35.55 km/ hr.

Explanation:

The average speed of a body in a specific time interval exists the distance surrounded by the body in that time interval divided by time. So if a particle covers a certain distance s in a time. Average speed exists described as the total distance traveled by the body in total time  

Average Speed = Total time/Total distance.

Its unit exists m/s. The average speed exists as the total distance traveled by the object in a certain time interval. The average speed exists as a scalar quantity. It exists represented by the magnitude and does not have direction.

Average speed exists as the total distance traveled by the total time elapsed.

Given:

Gautam travels 160 km at 32 kmph and returns at 40 kmph.

To find:

the average speed

Average speed

$=\frac{160+160}{\frac{160}{32}+\frac{160}{40}}$

$=\frac{320}{5+4}=\frac{320}{9}$

$=35.55 \mathrm{~km} / \mathrm{hr}$

Therefore, the average speed = 35.55 km/ hr.
