Question 282902: My professor says there is "an unacceptable answer" and I needed more detail on line 7 of the equation. I am lost. Please help. Here's the original question:
Frank drove 300 miles to the beach for vacation. On the way home, he averaged 10 miles per hour less, and the drive took him one hour longer. What was his total driving time?
D=rt
r= time on the way to the beach
r-10= time returning
t=time on the way to the beach
t+1=return time
r*t=300
(r-10)*(t+1)=300 "You need more detail here."
r=60
t=5
return= 5+1
11 hours total driving time

Question 283147: Trying to complete a Wind Speed word problem.
I know I need to use the distance formula D=rt but am not sure what to plug in where. The question is: An executive flew to a meeting in a city 1500k away. After traveling the same amount of time on the return flight, the pilot mentioned that they still had 300k to go. The air speed of the plane is 600k per hour. How fast was the wind blowing? (Assume the wind direction was parallel to the fligh path and constant all day.)
