Answer:
Suppose you travel a distance of 100 miles, and it takes 1 1/2 hours to do it. Your average speed is then 100 miles divided by 1.5 hours which equals 66.67 miles per hour.
Step-by-step explanation:
I'm not sure what your four step plan is, but here is how I would solve it:
50 rooms on each upper deck x 2 decks = 100 rooms
100 rooms x 1000 per room = 100,000
That leaves 48 rooms on the 2 lower decks, so 48/2=24 rooms per lower deck
48 rooms x 900 per room = 43,200
100,000 + 43,200 = $143,200 (maximum room sales amount)
Hope this helps!! :)
Answer:
6 hours
Step-by-step explanation:
$16/2=$8 per hour
$8x6=$48
Step-by-step explanation:
The way to find missing numbers in equivalent ratios is to multiply the means (the first denominator and the second numerator) and multiply the extremes (the first numerator and the second denominator). It sounds really complicated, but it is quite simple =)
2/5 = x/10
The means in this equivalent ration are 5 and x. The extremes are 2 and 10.
5x = 20
Now solve =)
x = 4
That was pretty simple. Let's move on to the next one. Do exactly the same thing here:
4/10 = 6/x
60 = 4x
15 = x
That was pretty simple, too! Keep going!
6/15 = x/25
15x = 150
x = 10
All of these should be equal, so check them by dividing:
2/5 = 0.4
4/10 = 0.4
6/15 = 0.4
10/25 = 0.4
They all check out, so these are your answers: 2/5, 4/10, 6/15, 10/25
I really hope this helps you =)
