She cover more distance after rest 101.7-88.4625=13.2375

Answer: Selena drove more after rest stop than before rest stop by 13.24 hours.

Step-by-step explanation:

Since we have given that

Number of hours Selena takes before rest stop = 1.75 hours

Speed at which she is driving before rest stop = 50.55 miles per hour

Distance = Speed × time

[tex]Distance= 50.55\times 1.75=88.46\ miles[/tex]

Number of hours Selena takes after rest stop = 2.25 hours

Speed at which she is driving after rest stop = 45.2 miles per hour.

Distance = Speed × time

[tex]Distance= 45.2\times 2.25=101.7\ miles[/tex]

Selena drove more after rest stop than before rest stop by

[tex]101.7-88.46\\\\=13.24\ miles[/tex]

Hence, Selena drove more after rest stop than before rest stop by 13.24 hours.
