h I can go 480 km in 4 hours. .
What is my speed?
Answers
Step-by-step explanation:
First, you must make sure that the problem to solve is in compatible units of measurement.
To begin, 480 km is 18,897,600 inches. Write that down.
Next, 1/8 of a mile equals one furlong.
There are seven days in a week.
There are two weeks in a fortnight.
12 inches equals one foot.
One mile equals 5,280 feet.
I think that covers the basics.
18,897,600 inches is 1,574,800 feet.
Since a furlong is 1/8 of a mile, and a mile is 5,280 feet, a simple division will show that 660 feet equals one furlong. Therefore 1,574,00 feet equals 2,384.85 furlongs.
Four hours is 1/6 of a day, or 1/42 of a week. Since a fortnight is two weeks, four hours comes to 1/84 of a fortnight.
Finally we have the units of measurements to solve this difficult problem.
Terry has traveled 2,384.85 furlongs in 1/84 of a fortnight. So clearly the answer is 200,327.4 furlongs per fortnight.
As you can see, with a little forethought and suitable care in choosing your units of measurements, these problems which might seem daunting at first are actually quite easy to solve.
Answer:
480 km * 1,000 = 480,000 meters
480,000 meters * 3.28 ft/meter = 1,574,400 lf
1,574,400 lf / 5,280 lf/mile = 298.18 miles.
4 hours times 60 minutes/ hour = 240 minutes
298.18 miles/240 minutes/hour = 1,24 miles per minute.
1.24 mile's per minute * 60 minutes per hour equals 74.55 mph
Answer: 74.55 mph.
