A car moves alone a straight path it covers the first half of the distance at the rate of 40km/h and second half at 60km/h find the magnitude of average velocity?

Answer 1

Answer:

A car moves alone a straight path it covers the first half of the distance at the rate of 40km/h and second half at 60km/h find the magnitude of average velocity?

Answer 2

Answer:48 km/h

Explanation: V₁= 40km/h,  V₂ =60km/h

∴ Average velocity =  2V₁V₂/V₁+V₂

⇒2 (40)(60)/40+60

= 2*2400/100

=4800/100

=48km/h
