Question

Answer 1

the answer is 90 miles

Answer 2

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

Explanation:

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

• Speed: x
• Time: 2 hours

if Distance = speed x time

d = 2x

If she drives 15 mph slower:

• Time = 3 hours
• Speed: x -15

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
