The winner of the 2008 Iditarod Trail Sled Dog Race was Lance Mackey. The course is 1112 miles long. His time was 9
days, 11 hours, 46 minutes, and 48 seconds.
Part A
What was Mackey's average speed in miles per hour? Round your answer to the nearest hundredth.

miles per hour
Part B
Imagine you are watching the 2008 race and Mackey is at the one-quarter mark. How many miles has he
traveled?

miles
Part C
If Mackey is traveling at the average speed you determined in part (a), how many miles will he travel in half a day?

miles
Part D
If y represents the distance and t represents the time, write an equation to represent this situation.

A: aproximately 4 miles per hour

B: 278 miles

C: 48 miles

Step-by-step explanation:

PLATO

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
