Question

an object is moving at a speed of 4 feet per minute. Express this speed in miles per week. Round your answer to the nearest hundredth.

Answer 1

7.64 miles/week

Explanation:

recall the following conversions

1 mile = 5280 feet or 1 foot = 1 /5280 miles

also

1 week = 7 days = 7 x 24 hours = 7 x 24 x 60 = 10080 min

We are given 4 feet /min. We can apply the above conversions to this to get:

4 feet/min

= 4 feet/min x (1/5280) miles/foot

= (4/5280) miles / min

= (4/5280) miles/min x 10080 min/week

= (4/5280)(10080) miles/week

= 7.636363 miles/week

= 7.64 miles/week (nearest hundredth)
