Step-by-step explanation:
the standard measure for speed is
miles per hour.
now we got as measurement
3 miles per 1/4 hour.
to give the standard speed or "unit rate" we assume that the bicyclist maintains the same speed for a whole hour.
and the question is : how many miles is he traveling then in that 1 hour ?
to answer this we have to check how often the actually measured unit of time fits into 1 hour.
1/4 hour fits 4 times into 1 hour.
and that factor applies now also to the miles to keep the value of the rate or ratio unchanged :
miles/time × a/a = miles×a/(time×a)
so that (time×a) = 1 hour
and so, he traveled 3×4 = 12 miles per hour.
Answer:
factors of 125 are:
1, 5, 25, 125
I'm not sure what u mean..... if you want to find hcf of a value then there has to be two value example: hcf of 125 and 225
Answer:
7 seconds
Step-by-step explanation:
set the equation to 0 because the water is the 0 point, and solve, you will get 7 and -5. It is not possible to have negative seconds so 7
