---
9(m/s)(1km/1000 m)(8 *3600s/8 hr) = (9*1*8*3600/1*1000)(km/8 hr)
= (259200/1000)= 259.2 (km/8 hr)

You can put this solution on YOUR website! At an average speed of 9 m/s, how many kilometers can a cyclist travel in a 8 hour day?
1st find out how many secs are in 8hrs
8(60mins)=480mins(60secs)=28800
9m/s =Xm/28800s xm=9(28800)m
259200m we know that 1km=1000m
divide 259200/1000= 259.2km
You can put this solution on YOUR website! How many seconds in an hour? sec = min min = hr sec/min x min/hr = sec/hr
Notice that the min units cancel out because
(sec/min) x (min/hr) is the same thing as (min/min) x (sec/hr)
How many sec are there in an 8 hr day? sec/hr x hr/day = 28800 sec/day
Notice that (sec/hr) x (hr/day) = (hr/hr) x (sec/day), and
(hr/hr) x (sec/day) = sec/day
-------------------------------
How many km in m? m x km/m = km
The cyclist travels km/sec (km/sec) x (sec/day) km/day
The cyclist travels 259.2 km in an 8 hr day
You can put this solution on YOUR website! There are no "8 hour days"
He travels the distance calculated (by others) in 8 hours.
Whether it's 8 hours/day, or 8 hours/month makes no difference. It's 8 hours.
