Question

Heidi walks 3 miles per hour and chris walks 20,000 feet per hour. About how much faster is Chris walking than Heidi, in feet per minute?

(1 mile=5,280 feet)

Answer 1

his gives us that Chris is walking 69 feet per minute faster than Heidi.

Explanation:

1 mile is equal to 5,280 feet, we can multiply 3 by 5,280 to find that Heidi is walking 15,840 feet per hour.

Next, we need to convert both speeds to feet per minute. Since there are 60 minutes in an hour, we can divide both speeds by 60 to convert them to feet per minute. This gives us that Heidi is walking 264 feet per minute and Chris is walking 333 feet per minute.

Finally, to find out how much faster Chris is walking than Heidi, we can subtract Heidi's speed in feet per minute from Chris's speed in feet per minute.
