A car travels at 30 mph can stop in 100 feet. What distance might it stop in when traveling at 70 mph?
d = (70/30)^2 * 100 Ft = 544.4 Ft^2.
To find out the stopping distance of a car traveling at 70 mph, we can use the concept of "stopping distance proportionality." Stopping distance is typically influenced by factors such as speed, braking ability, and road conditions.
In this case, we have two sets of data:
Car 1:
Speed = 30 mph
Stopping Distance = 100 feet
Car 2:
Speed = 70 mph
Stopping Distance = ?
To determine the stopping distance for Car 2, we can set up a proportion by equating the ratios of speed to stopping distance for the two cars:
(30 mph / 100 feet) = (70 mph / x)
Here, x represents the stopping distance for Car 2.
To solve for x, we can cross-multiply and solve the equation:
30 mph * x = 100 feet * 70 mph
Multiply the values on each side:
30x = 7,000
Now, isolate x by dividing both sides of the equation by 30:
x = 7,000 / 30
x ≈ 233.33
Therefore, the car traveling at 70 mph might stop in approximately 233.33 feet.
