The required value of the y for (1,40) and (3,y) points of car speed appear on a graph of the distance of the car over time is 120.
Given that,
A car is traveling at a steady rate of speed. the points (1,40) and (3,y) appear on a graph of the distance of the car over time. what is the value of y is to be determined.
What is speed?
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here on the graph coordinate of x represents the distance traveled and the coordinate of y represents the time taken to travel that distance.
so points (1,40) and (3,y),
speed = distance / time
1 / 40 = 3 /y
y = 120 units
Thus, the required value of the y for (1,40) and (3,y) points of car speed appear on a graph of the distance of the car over time is 120.
