Average speed is given by total distance traveled divided the total time taken.
Given that the distance from Mason's home to their son's college campus is 154 miles, then a round trip (to and fro) <span>from their house to their son's college campus will be 2 * 154 = 308 miles and the journey took 5 and a half hours.
Therefore, the average speed is given by:

Answer: x = 10 and y = 3
Step-by-step explanation:
Due to the x rule, (5x - 17) = (3x + 3)
If we add 17 to both sides:
5x = 3x + 20
Take away 3x from both sides
2x = 20
Divide by 2:
X = 10
This means that (5x - 17) = (3x + 3) = 33
Since all angles must add to 360, the top angle = (360- (33*2)) /2
(360-66) /2
294 /2
147
This shows that 9x - 19y = 147
90 - 19y = 147
Minus 90 both sides
19y = 57
Y = 3
So, x = 10 and y = 3
For number 1, theat is not a right triangle as a squared plus b squared does not equal c squared
