Answer:
To equal the height of the Gateway Arch in St. Louis, it would take <u>76810 half dollars.
</u>
Explanation:
If the Gateway Arch in St. Louis is 630 feet high, how many half dollars will it take to equal the height if each half dollar is 2.15mm thick?
First, we convert the ft to cm and the cm to mm.
- 1 ft = 30.48 cm
630 ft = 19202.4 cm
- 19202.4 cm = 192024 mm
Now, if a half dollar is 2.15 mm thick, how many half dollars would it take to equal the height of 192024 mm?
1 half dollar = 2.15 mm
X = 192024 mm
X = 192024 mm / 2.15 mm
X = 76810 half dollars.

All you have to do in convert two units. You need to know that there are 3600 seconds in an hour, and one kilometer is ~3,280.8399 feet. 3,280.8399 * 112 is equal to 367454.0688 feet per hour. Now divide it by 3600 to get it into seconds. That is equal to 102.07057466666667 feet per second. That's your answer.
