Toby skated from his house to the beach at a constant speed of 888 kilometers per hour, and then skated from the beach to the park at a constant speed of 777 kilometers per hour. The total distance Toby skated was 202020 kilometers, and it took him twice as long to get to the park.

Let bbb be the number of hours it took Toby to skate from his house to the beach, and ppp the number of hours it took him to skate from the beach to the park.

Which system of equations represents this situation?

Let the time taken to get to the beach==T

Then, time taken to get to the park ==2T

 

8T  +  7(2T) ==20, solve for T

 

T ==10 / 11 ==54.545454......minutes - time taken to get to the beach

54.545454......  x   2 ==109.090909.......minutes - time it took him to get to the park.
