Texting While Driving Corrections

Texting While Driving Data:

Prediction: We predict the car will travel 0.02815 in 2.38 seconds at a constant velocity of 45 m/h.

distance = 45 miles = 45 miles = x miles 
time           1 hour        60 min      1 min

60x = 45       x= .75 miles per 7 min
60      60

.75 miles =  75 miles
1 min             60 sec

After setting up a proportion and canceling the units until it was miles/ seconds, we cross multiplied the equation to find the variable x, which represents miles:

75 miles  =  x miles        x= 0.02875
60 sec          2.3 sec

Therefore, in 2.3 secounds the car would travel about .03 or .02875 seconds at a constant velocity of 45 m/h.

This motion map describes the cars motion because it shows that it is moving at a constant velocity. The velocity vs. time graph shows how the car moves at a constant velocity, from an origin of 45 m/h. The position vs. time graph shows how the cars position changes, but the distance per second is consistent throughout the movement of the car.
