Final answer:
The question is about distance, time, and rate in physics. The answer explains how to calculate speed using the given equation and how to find the spreading rate for both plates.
Step-by-step explanation:
Distance/Time = 1/2 Rate (multiply by two to get spreading rate for both plates)
In physics, speed is defined as distance divided by time. To calculate speed, we need to know the distance and time involved. In this equation, the distance is represented by the numerator and the time is represented by the denominator.
To find the spreading rate for both plates, we can multiply the rate by 2. This will give us the speed at which the plates are moving apart or spreading.
Your complete question is: 6) By knowing the age of the ocean floor and the distance from the ridge, you can calculate plate motion along the Mid-Atlantic Ridge, which is also the spreading rate. Find the two black dots in the Atlantic Ocean. The dots are 5000 km apart and the green color of the ocean floor indicates that they are 100 million years old. What is the spreading rate of the Mid-Atlantic Ridge at this location Report the rate of movement in cm/year (centimeters per year). Since the ocean floor moved the same distance on either side of the ndge, you need to divide your result by two Please show your calculations Remember that a rate of movement is distance per time (or distance over time). Since you report the rate of movement in cm/year, you will need to convert the units of time and distance that you start out with Here are some useful unit conversions 1 km 1000 m, 100 cm = 1 m (km = kilometer, m=meter) You are using the metric system because that's what's normally used in science, so I'd like you to get more familiar with this system. Hint. You might want to use cross multiplication for these calculations
