Sadie, Ariana and Sarah are running a relay race. Each part of the race is a different length and covers different terrain. It takes Sadie 2 hours to run through the forest at an average speed of 3 miles per hour. Ariana sprints across the open field on her section at 6 miles per hour for half an hour. If Sarah runs along the beach at four miles per hour and their total time for the race is four and half hours, what is the total distance of the race?
How many miles did Sadie run? ** Sadie ran for 3 miles/hour * 2 hour = <<3*2=6>>6 miles.
How many miles did Ariana run? ** Ariana covered a distance of 6 miles/hour * (1/2) hour = 3 miles.
How many hours did Sarah run? ** Sarah ran for 4.5 hours – 2 hours – 0.5 hours = <<4.5-2-0.5=2>>2 hours.
How many miles did Sarah travel? ** In this time, Sarah traveled a distance of 4 miles/hour * 2 hours = <<4*2=8>>8 miles.
What is the total distance of the race? ** The total distance for the race was 6 miles + 3 miles + 8 miles = <<6+3+8=17>>17 miles.
