a machine paints 340 toy boats in 45 minutes which expression equals the unit rate per hour
Very simple, 340/45 which equals 7.5
Then 7.5 * 60 = 453.3 Glad I could help :)
To find the unit rate per hour, we can set up a proportion using the given information. Let's start by converting the 45 minutes to hours.
There are 60 minutes in 1 hour, so 45 minutes is equivalent to 45/60 = 0.75 hours.
Now, we can set up the proportion:
Number of toy boats / Time (in hours) = Unit rate per hour
340 toy boats / 0.75 hours = Unit rate per hour
To simplify the expression, we divide the number of toy boats by the time in hours:
340 / 0.75 = 453.33
Therefore, the unit rate per hour is 453.33 toy boats per hour.
