Question

What is the speed (km/hr) of section (line) A in our motion graph? Hint: slope=speed

1) 0. 003 km/hr
2) 12 km/hr
3) 60 km/hr
4) 300 km/hr

Answer 1

Speed = 300 km / h

Step-by-step explanation:

Given:

Total distance = 60 km

Total time taken = 0.2 hour

Find:

Speed

Computation:

Speed = Distance / Time

Speed = 60 / 0.2

Speed = 300 km / h
