Today in class we started a new unit called Moving Straight Ahead. We got put into groups, went in the hallway and recorded the amount of time it took for one person to walk 10 meters.
For example, in my group,
I walked 10 meters in 7 seconds.
Adain walked 10 meters in 7 seconds.
Kiera walked 10 meters in 8 seconds.
Matt walked 10 meters in 10 seconds.
Then with our groups we worked on problem 1.1. We had to find the unit rate for our times, how long it would take to walk a certain distance, what distance we could walk for a period of time and an equation that represents the distance(d) in meters that you could walk in (t) seconds if you could maintain the same pace.
For Example:
10 meters walked in 7 seconds= 1.4 meters walked in 1 second.
this way you could figure out how long it would take you to walk 500 meters...
500/1.4=357.7 Therefore it would take someone 357.7 seconds to walk 500 meters if they are going at a rate of 1.4 meters per second.
We also learned how to figure out the distance for a certain time frame using our rate.
For Example:
10 minutes=600 seconds
rate- 1.4 meters in 1 second
1*600=600
1.4*600=840
Therefore at the rate of 1.4 meters per second someone could walk 840 meters in 600 seconds or 10 minutes.
Lastly we learned how to make an equation: What distance you could walk for a period of time and an equation that represents the distance(d) in meters that you could walk in (t) seconds if you could maintain the same pace.
the equation was for the rate of 1.4 meters in 1 second, d=1.4t
This is because to find out the number of meters you could go for any number of seconds the distance would have to be equal to to the unit rate of meters, multiplied by any number of seconds.
This is what we did today in class=]
