Question

A car moves at 60km/hr for 2km and 40km/hr for next 2km find average speed of the car

Answer 1

average speed =Total distance / Total time. t=60*2=120 and. t=40*2=80. <v>=2+2/120+80 =4/200. =2/100. = 1/50. average speed = 0.02

Answer 2

Answer:

given:

s=60km/h

d=2km

s=40km/h

d=2km

Explanation:

(s=60×2=120)

(s=40×2=80)

average speed =total distance/ total time taken

v=2×2/120×80

=4/200

=2/10

v=0.02
