In a bicycle race, bicyclists rode

How long was the entire bicycle race? Write an equation and then use it to find your answer. Remember to define your variable.

Create a table to represent the race.

We know that the bicyclists rodemiles or of the race.

The rest of the race issince: (total) (first day) (rest of the race) -The bicyclists rode

miles which was of the entire race.

-Letrepresent the total race length.

Set up an equation and solve:**SECTION****DISTANCE****PERCENT**A

B

unknown

The total length of the race is

miles. If bicyclists rode

of the race on the second day, how many miles did they ride on the second day? We already know that the entire race is

miles.

On the second day, they rodeof the entire miles.

Set up an equation and solve:(Let represent the miles for the second day)After completing the first two days as described in parts (a) and (b), the bicyclists have what percentage of the race left to ride?

The bicyclists rode

the first day and the second day. Add

and to find the total percent the bicyclists rode the first two days. Subtract the total percent for the first two days from

(Percent of the entire race). How many miles do the bicyclists have left to ride?

Add the distance the bicyclists rode on day

of the race (answer to part (b)) to the distance they rode on day ( miles) and subtract this from the total distance of the race (answer from part (a)). The bicyclists have

miles left to ride.
