If a bicycle travels 15 m in 2 seconds, what is the speed in km/h?

To convert the speed from meters per second to kilometers per hour, you need to multiply by 3.6.

In this case, the speed is 15 m/2 s = 7.5 m/s.

Therefore, the speed in km/h is 7.5 m/s * 3.6 = 27 km/h.

(15 m / 2 s) * (3600 s/1 hr) * (1 km / 1000 m) = 15 * 1.8 km/hr
= 27 km / hr sure enough
