Question

a glacier is a giant mass of rocks and ice that flows downhill like a river. a certain glacier moves at a rate of 21 inches a day. find the distance in feet the glacier moves in a year. (assume 365 days a year.) l = □ ft (round to two decimal places as needed.)

Explanation:

Step1: Calculate total inches in a year

The glacier moves 21 inches a day and there are 365 days in a year. So the total inches in a year is $21\times365 = 7665$ inches.

Step2: Convert inches to feet

Since 1 foot = 12 inches, to convert inches to feet, we divide the total number of inches by 12. So the distance in feet is $\frac{7665}{12}=638.75$ feet.

Answer:

638.75
