Since you need to go there and back multiply 930 by 2. 930*2=1,860. Divide 1,860 by 30 to get 62. You need 62 gallons of gas to get to your friends house and back. I hope this helps! ;)
Answer:
2x-3=2x-4
Step-by-step explanation:
2x-3=2x-4
-3=-4
Not true. Thus, no solution.
The aircraft is already 300 miles west of A,
so it only has (2490 - 300) = 2190 more miles to go.
(2190 miles) / (600 miles/hour)
= (2190 / 600) hours
= 3.65 hours
= 3 hours 39 minutes more.
