Question

if you walk for 30 second at speed of 2m/s and run for 2minutes at 1.5m/s along the same straight track .find the average speed your self?​

Answer 1

1.6 m/s

Step-by-step explanation:

Avg. Speed = total distance/total time

d1 = speed x time = (2 m/s)(30 s) = 60 m

d2 = (1.5 m/s)(120 s) = 180 m

d-total = 60 m + 180 m = 240 m

t-total = 30 s + 120 s = 150 s

Avg speed = 240 m / 150 s = 1.6 m/s
