Question

The fastest average speed by a cyclist across the continental United States is 15.4 mph, by Pete Penseyres. If he traveled a total distance of about 3107.5 miles at his speed, find his time cycling. Write the time in days, hours, and minutes.

Answer 1

In 1986, Pete Penseyres set the all-time RAAM speed record of 15.4 mph over a course of 3107

miles with a time of 8d 9h 47m. It’s a record that has stood for more than 20 years. Just how fast

is that?

The winning speed in 1982 and 1983 was still under 13mph. In 1984, Penseyres pushed that to

13.29mph. In 1985, Jonathan Boyer set the still standing rookie record of 9d 2h 6m for an average

speed of 14.31 mph over a 3120 mile course. Pete came back in 1986 on a virtually identical

course to 1985 and set the record beating Boyer’s speed by 7.6%.

In 1992, Rob Kish set the fastest ever RAAM time of 8d 3h 11m on a course that was 2911 miles

long for an average speed of 14.91 mph, which stands as the second fastest speed. At Pete’s pace

of 15.4 mph that would have been 7d 21h 1m. Pete’s pace was still 3% fast on a course 200 miles

longer. Over 200 hours of racing, 3% is 6 hours.

In Lance Armstrong’s seven Tour de France wins, his average time was about 86 ½ hours. His

average margin of victory was about 6 minutes. 6 minutes out of 86 ½ hours is just 0.11% (onetenth

of one percent).

In 1986, the second place finisher was Lon Haldeman at 9d 8m 2m, Lon’s best time. Pete’s

margin of victory was 11.03%. The average margin of victory in RAAM is 3.6% or about 8

hours.

that might be ur answer :/

Answer 2

Pete Penseyres' cycling time is 8 days 4 hours and 8 minutes.

What is average speed?

"It is the total distance traveled by the object in a particular time interval."

What is the formula of average speed?

"speed = total distance /total time"

For given question,

The fastest average speed by a cyclist Pete Penseyres is 15.4 mph

⇒ average speed (s) = 15.4 mph

he traveled a total distance of about 3107.5 miles at his speed,

⇒ d = 3107.5 miles

Let 't' be his cycling time.

Using the formula of average speed,

$\Rightarrow s=\frac{d}{t}\\\\\Rightarrow 15.4=\frac{3107.5}{t}\\\\ \Rightarrow t=201.78\\\\\Rightarrow t=201.8~~hours$

This means his cycling times is 201 hours and 8 minutes.

Now, we convert 201 hours in days.

We know, 1 day = 24 hours

$\Rightarrow t=\frac{201}{24}\\ \\\Rightarrow t=8.4~~days$

This means, time is 8 days and 4 hours

Therefore, his cycling time is 8 days 4 hours and 8 minutes.
