Question
The s-t graph of an athlete’s motion is given below. The total distance covered is ______ km.
Hint:
24 km
The correct answer is: 24
The total distance covered by an athlete is 24 km
Justification:
Distance from A to B = 3-0 = 3 km
Distance from B to C = 3-3= 0 km
Distance from C to D = 12 - 3 = 9 km
Distance from D to E = 12 - 12 = 0 km
Distance from E to F = 12 - 0 = 12 km
Total distance covered by an athlete = 3+9+12 = 24 km
