half at 60kmh-1
of the
what is the average
espeed
car?​

Answer 1

Answer:

48km/h

Explanation:

use formula

=(2uv) /(u+v)

Answer 2

Answer:

48

Explanation:

firstly we assume half distance be x and the next will be by condition also x

we know that

Average speed=total distance/total time.....(1)

so we calculate total time ie. t1=x/40and t2=x/60

so total time=t1=x/40+ t2=x/60

and total distance is x+x=2x

soabove value put in (1)
