Step-by-step explanation:

Given :

Carlos and Maria drove a total of 258 miles in 5 hours.

Carlos drove the first part of the trip and averaged 53 miles per hour.

Maria drove the remainder of the trip and averaged 51 miles per hour.

To Find : For approximately how many hours did Maria drive? Round your answer to the nearest tenth if necessary.

Solution:

Carlos and Maria drove a total of 258 miles in 5 hours.

Let t be the time for which Carlos drove

So, Maria drove for hours = 5 - t

Speed of Carlos = 53 miles / hr

Distance covered by Carlos =

                                              =

Speed of Maria = 51 miles per hour.

Distance covered by Maria =

Total Distance  =

Since we are given that Carlos and Maria drove a total of 258 miles

So,  

Carlos drove for 1.5 hours

Maria drove for hours = 5 - t = 5-1.5 =3.5 hours

Hence Maria drove for 3.5 hours.
