Kelly drives 448 miles on the highway to visit her xousin. She uses cruise control to drive at a constant speed . Kelly travels 192 miles in the first 3 hours. At that rate, how long will the trip take?

Respuesta :

192 miles divided by 3 hours = 64 miles per hour

448 miles / 64 miles per hour = 7 hours total for the trip

Answer:

Trip will take 7 hours to complete.

Step-by-step explanation:

Kelly drives 192 miles in the first 3 hours.

Speed of Kelly to cover 192 miles = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

                                                        = [tex]\frac{192}{3}[/tex]

                                                        = 64 miles per hour

Kelly travels with the same speed to cover the whole distance.

Therefore, time taken to cover 448 miles = [tex]\frac{\text{Distance}}{\text{Speed}}[/tex]

= [tex]\frac{448}{64}[/tex]

= 7 hours

Kelly will meet his cousin after 7 hours.
