Question

Mrs. Rosso has to travel 390 miles on a highway. She drives 130 miles in 2 hours. If she 7 hours to travel at that rate, will she arrive at her destination on time?

Answer 1

Answer: yes

Explanation:

If she travels at that rate she gets 65 miles per hour. 65 multiplied by 7 is 455, so she will get there before the 7 hours is up.

Answer 2

Explanation:

Find the miles per hour. Divide 130 with 2

130/2 = 65

Mrs.Rosso travels 65 miles per hour. She has 7 hours to travel. Multiply 7 with 65:

65 x 7 = 455

455 > 390 ∴ If everything stays constant, Mrs.Rosso will arrive to her destination on time.
