Due to continental drift, the North American and European continents are drifting apart at an average speed of about 3 cm per year. At this speed, how long (in years) will it take for them to drift apart by another 658.1 m?

658.1m / .03m/yr = 21936.7 yr

To calculate how long it will take for the North American and European continents to drift apart by another 658.1 m at an average speed of 3 cm per year, we can use the following steps:

Step 1: Convert the given distance into centimeters.
658.1 m = 65,810 cm (since 1 meter = 100 centimeters)

Step 2: Divide the distance by the speed to find the time.
65,810 cm ÷ 3 cm/year ≈ 21,936.67 years

Therefore, it will take approximately 21,936.67 (or rounded to 21,937) years for the continents to drift apart by another 658.1 m.
