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.
