Answer:
18 km/hr
90 km
Step-by-step explanation:
We know that there are
1000 m = 1 km
and
3600 s = 1 hr
We need to convert m/s to km/h
5 m 3600s 1 km 18000km 18 km
------ * ------------ * ------------ = --------------- = ------------
s 1 hr 1000m 1000 hr hr
It is 18 km/hr since the units cancel.
We want to know how far the cyclist travels
d=rt
We know the rate 18km/hr and the time = 5 hr
d = 18 km/hr * 5 hr
d =90 km
