I need help please and quick because I’m getting a migraine because I’ve been thinking so much

Lizette is training for a marathon. at 7: 00 she left her house and ran until 8: 30, then she walked until 11: 30. she covered a total distance of 18 miles. her running speed was six miles per hour faster than her walking speed. find her running and walking speeds in miles per hour.

The balance of susu's savings account can be represented by the variable b. the inequality describing her balance b > $30 . which could be a solution to the inequality?

100 points and 1- -12=y-36 2- x/25=-25 3- -n=40
