It takes adi 2 hours to drive from home to her office and 3 hours if she drives 15 mph slower. what is the distance between adi's house and the office?

The distance between Adi's house and the office is 90 miles.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information give:

if Distance = speed x time

d = 2x

If she drives 15 mph slower:

d = (x-15) 3

d=d

2x = (x-15)3

Solving for x

2x = 3x-45

45=3x-2x

45=x

Replacing x in any of the two expressions;

d = 2 x = 2 (45) = 90

d =90 miles

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
