Question

A car moving with uniform acceleration covers first half of a certain distance with speed of 60 km per hour and second half with distance speed 40 km per hour then its average speed from this whole journey is

Answer 1

Answer:

$average \: speed = \frac{60 + 40}{2} = \frac{100}{2} \\ \\ = 50 \frac{km}{h} \\ \\ \: mark \: it \: as \: brainliest \: and \: \\ follow \: me$

Answer 2

Answer:

Avg speed = 125/9 m/s

Explanation:

For average speed use the formulae :

avg speed = V1 + V2 / 2

                  = 60 + 40 /2

                  = 50 Km/h

                  = 50 x 5/18 = 125 /9 m/s

Help me out with a "brainliest"
