provide detailed answer with formula
pls don't post irrelevant. answer..​

Answer 1

speed of the car from point A to B = 40 km/h

speed of the car from point B to A = 60 km/h

$average \: speed = \frac{speed \: 1 \: + speed \: 2}{2}$

$average \: speed = \frac{40 + 60}{2}$

$average \: speed = \frac{100}{2}$

average speed = 50 km/h
