A skydiver accelerates from 20 m/s to 40 m/s in 2 seconds. What is the skydiver's average acceleration?

10m/s²

Explanation: Acceleration= (v-u)/t

                                                 So here it’s (40-20)/2

                                                 Which is equal to 10

i think it would be 80 km/h because 30 + 50 = 80 (sorry if this not the right answer i'm trying my best)

568.98
