Bryce, a previous winner of the contest, made a trip of 360 miles in a 6.5 hours. At this same average rate of speed, how long will it take Bryce to travel an additional 300 miles so that he can judge the contest?

5.42 hours

Step-by-step explanation:

Let x represent time taken to complete 300 miles.

We have been given that Bryce a previous winner of the contest, made a trip of 360 miles in a 6.5 hours.

We will use proportions to solve our given problem since rates are same for both distances.

Upon substituting our given values in above proportion, we will get:

Cross multiply:

Therefore, it will take approximately 5.42 hours to travel additional 300 miles.
