A log with a radius of 2.5 feet is rolled up a hill. If it takes 30 seconds to roll the log one complete revolution, approximate
ly how many minutes will it take to roll the log 75 yards? [3 feet = 1 yard] 5 7 10 12 15
1 answer:
Answer: 45minutes
Step-by-step explanation:
Since it takes 30seconds to roll a log of 2.5feets up the hill, it will take 25×225/2.5 seconds to roll a log of 225feets(75yards).
*Note that
3feets= 1yard
xfeets = 75yards
x = 75 × 3
x = 225feets
2.5feets = 30seconds
225feets = y
y = 225×30/2.5
y = 2700seconds
It will take 2700 seconds (45minutes) to roll up 75yards(225feets) of log
