Answer:
Smallest rate for the train is 50 mph and largest is 60 mph.
For the bus it is 25 and 30 mph.
Step-by-step explanation:
If the speed of the train is 2x then speed of the bus is x mph, and the train travels twice as far as the bus in a given time.
Distance = speed * time
For the largest rate:
d = 2x * 0.5 for the train
x = d
0.5d = x for the bus
d - 0.5d = 15
0.5d = 15
d = 30
So the rate for the train = 30 / 0.5 = 60 mph.
In a similar fashion we can show that the smallest rate for the train is
25/ 0.5 = 50 mph.
So if ever looking for % of, and you have a calculator a very simple way of doing it is taking your actual amount ($74.00) and multiplying it by 0.26
0.26, mathematically is like saying 26% of
The answer is 19.24
You'll notice if you type 74 x 0.50 (which is 50%) you will get 37 -- exactly half of 74
