Khawla drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 10 hours. When Khawla drove home, there was no traffic and the trip only took 7 hours. If her average rate was 18 kilometers per hour faster on the trip home, how far away does Khawla live from the mountains? Do not do any rounding.

Step-by-step explanation:

v

v+18

v*10=(v+18)*7

v=42

42*10=420 (mi) <== answer

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
