Think about the units here, miles per hour. If you are given one value in miles and another value in hours, to get the units to match up you would divide the value in miles by the value in hours, in other words dividing 3.5miles by 1.5 hours.
ok i dont under stand that
So, doug is traveling 3.5 miles total, right? and he does that in 1.5 hours time. Follow so far?
where r u getting all these points and all that from
This is all just stated in the question. Taking it piece by piece can help you decide what is important in the word problem and what isn't. This problem deals with a person moving some distance in a given amount of time, so things like that he was canoeing don't matter. What matter here are the phrases "he rowed 3 and a half miles" , "1 and a half (hours)", and of course the question at the end asking for the average speed in miles per hour. Average speed is found by dividing the distance over the amount of time. The distance here is in miles, the amount he rowed. "3 and a half" translates to 3.5 in decimals. The time is 1 and a half hours, which translates to 1.5 in decimals. Therefore to find the speed you divide miles by hours, in other words \[3.5/1.5 \]
ok so wats the answer
Just divide 3.5 by 1.5, it's that simple.
hello r u gonig to answer
Sorry, yes that's right
ok than wats next
That should be all you have to do. 2.3 is your speed in miles per hour.
ok thx a lot
Happy to help :)
yea thx bye im closeing it i mean i allready did lol
