Answer: 2.5 hours is the answer
Step-by-step explanation:
It took Travis 2.5 hours to complete 3/4 of his trip. To find the average speed, we need to find his speed during 3/4 of the trip and then the 52.5 miles.
So you know that 52.5 is 1/4 of his total trip. That means if we multiply that by 3, that's how many miles he traveled in 2.5hrs. (157.5)
To calculate speed, divide distance by time.
For 3/4 of his trip (157.5), it took him 2.5 hours.
157.5/2.5 = 63mph
For the remaining 52.5 miles, it took him an hour.
52.5/1 = 52.5mph
Now average those two speeds to get the average speed for the whole trip.
(63+52.5)/2= 57.6mph
Answer:
16 years old
Step-by-step explanation:
22-38 = -16
The inverse of -16 = 16
Side 1+ side 2 + side 3=180 on a triangle. 180-56=124 124-66 because 124-56 =66 but X is the smaller side so 56 X=56 (i believe but could be wrong unsure I have a tendency to mess up a few calculations.)

Just replace the N of the function F(N) with the requested value - 10:
F(N) = 2N + 3
F(- 10) = 2 · (- 10) + 3 <em>now N has been replaced by - 10</em>
F(- 10) = - 20 + 3
<h2>F(- 10) = - 17</h2>
