What information do you need to know to calculate last year’s winning speed? Remember, the distance traveled (length of the course) is equal to the rate (boat’s speed) times the time.

1. Total distance

2. Shortest time taken

Step-by-step explanation:

Since it is a competition the distance will be the same for all participants.

therefore the information need is

1.  The total distance of the competition

2. The time taken by each participant to complete the race

The winning speed is the speed is given as the distance covered in the shortest possible time.

hence the winning speed is expressed as

winning speed= distance/short time taken

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
