1 minute and 20 seconds as a decimal = 1.333
60 minutes are in an hour
60/1.333 = 45
He is driving 45 miles per hour.
Given that the car consumes 6 liters of gas for every 100 kilometers it covers, then it needs to consume 4000(6)÷100 = 240 liters of gas to cover 4000 kilometers.
Since the cost of gas is $1.50 per liter, then 240 liters would cost (1.50)(240) = $360.
Since all of four friends would share the cost equally, then it will cost 360 ÷ 4 = $90 each person for the trip.

Answer: I think 27/2
Explanation:
Let number = x:
√(2x - 11) = 4
Now to get x, we undo the square root by squaring both sides:
[√(2x - 11)]² = 4²
(2x - 11) = 16
2x = 27
x = 27 / 2
