lesson :solve problems involving distance, rate and speed

isaac and alexa raced around the 2 km track by running. isaac run at 1 m/s. alexa run at the rate of 0.8 m/s each of them run once around the track.

how long did each child take to run once around the track who won the race.

to solve for the answer to the problem you need to use the four step in problem solving

step 1 step 1 understand the problem
answer each question about the problem
•what where Isaac and alexa doing?
•where did they race?

step2 plano what to do
answer each question below.
•what is asked
-the person who won the race
•what facts are given?

•how do you go about solving the problem
-find the amount of time each person completed running around the track then compare these amounts of time to see who finish the race first
•what should you do first
-signs the speed is in meters per second convert 2 km 2 meter then use the formula below

d
t = s​
