A car travels 240 km in 2.0 hrs and a sprinter travels a 100. m in 9.5 s. Which is traveling faster and by how much?

Car: (convert first the units)

240 km * (1000 m / 1 km) = 240000 m

2 hr * (3600 s / 1 hr) = 7200 s

v = d/t

v = 240000/7200

v = 33.33 m/s

Sprinter:

v = d/t

v = 100/9.5

v = 10.53 m/s

thus the car travels faster than sprinter by 33.33 - 10.53 = 22.8 m/s
