a car travels at an average speed of 30m/s for 0.8 h. find the total distance traveled in km.
.
Distance formula is:
d = rt
where
d is distance
r is rate or speed
t is time
.
Since rate is given as "per sec"
we can convert our "units" of time from hours to secs:
0.8 hr * 60 min/hr * 60 sec/min = 2880 secs
.
d = 30m/s * 2880 secs = 86400 meters
.
Now, we need to convert to km:
86400 meters * 1 km/1000 m = 86.4 km
