Answer:

1.25 hours (Or 1 hour and 15 minutes) and 14 MPH

Step-by-step explanation:

1. If it takes 1 hour to travel 48 miles, then you can subtract it from the 60 miles, and have 12 miles left. Divide 12 by 48, and you get 0.25, so if you add it together, you get 1.25. To check, 48 x 1.25 equals 60.

2. 270 minutes is equal to 4.5 hours. Divide 63 by 4.5, and you'll get 14 miles per hour. To check, 4.5 x 14 equals 63.

Answer:

Let me know if you want more explanation

Step-by-step explanation:

Alright, to solve for x we need 2 angles that are congruent or equal.

I'm going to use the two we will need later. KLN and MNL

Now to find x ^^

2x-18=x+6\\2x-18-x=x+6-x\\x-18=6\\x-18+18=6+18\\x=24

Now we just need to plug it into each angle. I'm going to show you them separately.

KLN=2x-18\\KLN=2(24)-18\\KLN=48-18\\KLN=30

MNL=4x-6\\MNL=4(24)+6\\MNL=102

should be right now.
