Final answer:
The glacier travels 0.567 cm in 81000 seconds and 816.774 cm in 3.7 years by multiplying the speed by the time. The conversion from years to seconds is used for the second part of the calculation.
Step-by-step explanation:
The question involves calculating the distance a glacier moves based on its speed and the time it travels. To find out how far a glacier advances at a speed of 7 × 10^-6 cm/s in 81000 seconds, we simply multiply the speed by the time:
Distance = Speed × Time
Distance = (7 × 10^-6 cm/s) × (81000 s) = 0.567 cm
To determine how far the glacier advances in 3.7 years, we need to convert years to seconds. Since there are 365 days in a year, 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute, we get:
Seconds in 3.7 years = 3.7 × 365 × 24 × 60 × 60 = 116,682,000 s
Now we can calculate the distance traveled in 3.7 years:
Distance = (7 × 10^-6 cm/s) × (116,682,000 s) = 816.774 cm
