Formula to calculate total distance:
Total Distance = average velocity * time
given data:
v1 = 3 km/h = 0.83 m/s
v2 = 4 km/h = 1.11 m/s
v3 = 6 km/h = 1.67 m/s
Average velocity = 0.83+1.11+1.67/3 = 1.203 m/s
Time = 1 hour - 50 minutes = 3600 seconds - 3000 seconds = 600 seconds
Putting these values in the formula:
Total distance = 1.203 m/s * 600 seconds
Total distance = 721.8 meter per second squared
or,
Total distance = 3.07091039 × 10^13 meters
is the required distance.
