10-7=3 so his rate is 18 boxes every 3 hours 18/3 is 6 boxes per hour, 12-7=5 hours 5 x 6 = 30 boxes by 12pm
Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr
One pack is $4.50.
To make it simpler with no equations, There are 2 packs of markers in-between 3 packs and five packs.
So, $9 divided by 2 packs is 4.5$,
And to prove this scenario right,
3 packs= $13.5. (3•4.5)
5 packs= $22.5. (5•4.5)
So between 5 packs and 3 packs,
There is a difference of 9 dollars,
Hence 3 packs of markers at $13.5,
5 packs is $22.5, so that is $9 less
Than 5 packs of markers.
Therefore one pack of markers is $4.50, by dividing 22.5 by 4.5 or 13.5 by 4.5 after figuring out the previous.
