To find the average speed in miles per hour, you will create a rate using the number of miles to the number of hours in 45 minutes.
54 miles in 0.75 hours (45 minutes)
To make this a unit rate or miles per hour, divide the number of miles by the time.
54/0.75 = 72 mph
The train traveled an average speed of 72 mph.
2x^2 - 5x - 3
x^2 - 5x - 6
(x + 1)(x - 6)
Hope this helps :)
