If you can tell me how you're supposed to figure it out.. that would be nice too.

Average speed
= 60 / 1.5 km / h
= 120 / 3 km / h
= 40 km / h

Let's see. If it took you 1.5 hours to go 60 kilometer you must have gone 20 kilometers every .5 hours so just double that and you get 40 kilometers per hour.
Here is the official math way of doing it. A proportion.
60/1.5hours = x/1hour (now cross multiply)
60 = 1.5 x (now divide both sides by 1.5)
40 = x

Rate*Time=Distance
Rate*1.5 Hours=60 Kilometers
divide each side by 1.5
Rate= 40 K/H

divide 60 by 1.5 to get 40. So the answer should be 40 kilometers per hour

average speed = 60/1.5 = 60*2/3 = 40 km/hr

Hi,
60 km / 1.5 hr = 40 km / hr.
As a check, you can figure that you travel 40 km in the first hour, and in the next half-hour, you travel
40 km / hour X .5 hour = 20 km.
So, your total distance traveled is 60 km.
:-)

is that really algebra ?
s x 1.5 = 60
s = 40

60/1.5
d=rt
^ meaning, Distance = Rate x Time.

60km - 1.5hours (90min)
30km - 45min
10km - 15min
40km - 60min (i hour)
So your average speed would be 40kilometers per hour
