Solve the problem.
You traveled 189 miles on 7 gallons of gasoline. At this rate, how many gallons of gasoline would you need to travel 297 miles?
Choose the best answer from the options below:
A 11
B 14
C 20
D 15.5
To solve this problem, we can set up a proportion:
7 gallons / 189 miles = x gallons / 297 miles
Cross multiplying, we get:
7 * 297 = 189 * x
2079 = 189x
Dividing both sides by 189, we get:
x = 2079 / 189
x ≈ 11
Therefore, we would need approximately 11 gallons of gasoline to travel 297 miles.
The best answer is A) 11.
To find out how many gallons of gasoline you would need to travel 297 miles at the same rate, we can set up a proportion:
189 miles / 7 gallons = 297 miles / x gallons
Now, we can cross multiply:
(189 miles) * (x gallons) = (7 gallons) * (297 miles)
Multiply both sides:
189x = 2079
Divide both sides by 189:
x = 2079 / 189
Simplify:
x ≈ 11
Therefore, you would need approximately 11 gallons of gasoline to travel 297 miles.
The correct answer is A) 11.
