The trip was 6 hours long.
Step-by-step explanation:
Given,
The time to go to the island = 1
hours.
The return trip took 3/4 of the time of the original trip.
To find the time of the trip.
Let,
The time of the original trip is x hours.
The time for returning = 
According to the problem,
1 + = x
or, x - = 
or, 
=
or, x = ×4 = 6 hours
Hence,
The trip was 6 hours long.
Step-by-step explanation:
calculate the each one then compare
hint :
mean : add all the numbers and divide by how many numbers there are .
median : the middle number . for example : 12345 . 3 is the middle number .
mode : the number that appears more often than the other numbers.
F(x) means y
so <span>f(x)→ ∞ as x→ -∞ and f(x) →∞ as x→∞ means
as x goes to the left </span><span>y goes up infinitely
as x goes the the right, y goes up intinitely
that would be the 4th graph
the parabola opening up </span>
Answer:
0.47
Step-by-step explanation:
47% is the same as 0.47.

Speed can be broken down to distance / time.
If we know Justin drive for 2 hours before lunch and his trip was 5 hours total, then we know he drove for 3 hours at the increased speed.
2 hours * the original speed will give us the distance traveled before lunch, and 3 hours * the increased speed will give us the distance traveled after lunch. The sum of these distances is 330 miles.
2x + 3(x + 10) = 330
5x = 300
The original speed was 60 mph.
