a person Can travel 120 miles in one direction. the return trip was accomplished at double the speed and took three hours less t
BaLLatris [955]
40 mph would be 120 miles in 3 hours (120/40)

80 mph is 120 miles in 1.5 hours(120/80)

3 - 1.5 = 1.5, not 3 hrs

Change the speed to 20 mph( 1/2 the speed) to double the hours.

20 mph = 6 hours(120/20)

40 mph = 3 hrs(120/40)

6 - 3 = 3 hours difference

Vedmedyk [2.9K]

Answer:

x=20 and y=100

Step-by-step explanation:

Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
