Jamie took 2 hour and 30 minutes to reach the because 5:30-3:00=2hours and 30 minutes.Raul took 1 hour 30 minutes to reach state park because 4:30-3:00=1 hour and 30 minutes.Since they went in opposite directions you can add the time to get 4 hour.It would take 4 hours to go from the beach to state park.There speed was 60 miles per hour since 240/60=4/1 mph.

Answer:
20x - 4
Step-by-step explanation:
4 less than 20 times some number
Let's break it up.
4 less than = -4
20 times some number = 20x (x is representing "some number")
So, let's put that together.
4 less than 20 times some number
20x - 4
You follow the rules for the quadratic formula, where
x= (-b +- √(b²-4ac) )/2a
Filling a, b and c in yields
x = (8 +- √(64-164) ) / 2 =>
x = (8 - √-100)/2 or x = (4 + √-100)/2
Well, √-100 = 10i, so then you simplify to the last answer, D:
x = 4-5i or x=4+5i
