Average speed = (total distance covered) / (time to cover the distance)
total distance covered = (4km + 2km + 1km) = 7 km
time to cover the distance = (32min + 22min + 16min) = 70 min
Average speed = (7 km) / (70 min)
Average speed = 0.1 km/minute
Hello!
We can use the kinematic equation:
a = acceleration (m/s²)
vf = final velocity (45 m/s)vi = initial velocity (25 m/s)
t = time (5 sec)
