Answer: 136 m
Step-by-step explanation:
For first interval,
Time = 2 hours 40 minutes = ![2+\dfrac{40}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=2%2B%5Cdfrac%7B40%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 18 m/h
Distance = 
[Formula : Distance=Speed x time]
For second interval,
Time = 1 hour 50 minutes = ![1+\dfrac{50}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=1%2B%5Cdfrac%7B50%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 24 m/h
Distance = 
Total distance = 48 m +88 m = 136 m
Hence, he went 136 m.

Answer:
11. AW║BY
12. DX║YZ
13. AW║YZ
14. AW║DZ
Step-by-step explanation:
11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.
12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.
13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.
14. Lines perpendicular to the same line are parallel.
