Question

Heather is driving her car on a business trip. She knows she will drive for more than 94 kilometers on the trip. Also, she will drive for less than 115 kilometers on the trip (so that her company can cover her gas expenses). She has 3 days left on the trip. Let x be the number of kilometers per day she will drive for those 3 days. (Suppose she will decide to drive the same distance each day.) She has already driven the car for 55 kilometers on the trip.

Answer 1

Answer: 13-20 km

Explanation:

94 < 55 + 3x < 115 Subtracting 55 from all parts of the inequality, we get: 39 < 3x < 60 Dividing all parts of the inequality by 3, we get: 13 < x < 20
