Look for the shortest time. The shortest time is fastest.
Think of the speed formula: speed = distance/time. You need tools for finding distance and time.
speed is increasing
Remember to draw a line dividing the curve in half. If the flatter part of the curve is first, then turns in to an almost-vertical, the motion starts out slow and increases.
Speed = distance/time; 150/2=75mph
between 6 and 7 seconds
The incline (slant) is steepest between 6 and 7 seconds. This means the distance in increasing a lot while little time is passing, so the speed is higher than other places on the graph.
travels at a constant speed, then suddenly stops
The diagonal line indicates a constant speed; the horizontal line shows a stop.
segment CD shows a time when the motion stopped
The horizontal line indicates a stop. Distance is not increasing, time is continuing to pass.
Mandy won the race
Mandy's incline is steeper. This shows that she traveled the same distance in less time. A steeper incline is a faster speed.
Crystal is decreasing; Lisa is increasing
Draw lines through the middles of the curves. Check to see if the curves start out more horizontal (slow) or more vertical (fast). Move from there to see if the curves end fast or slow.
Carlos won the race.
His incline is steeper, indicating a quicker amount of time.
a diagonal is a constant speed
the horizontal begins at 10 seconds (horizontals indicate a stop in motion)
it traveled 30 meters, stopped and returned to its starting point
there are diagonals with increasing distance, then a period of horizontal lines, followed by diagonals with decreasing distance
car 1 moved at a constant speed while car 2 stopped for 10 minutes
car 1 maintained diagonal lines the entire time, while car 2 had a 10 minute period of horizontals
the horizontal (indicating a stop in motion) begins at the 4th second
