An object is traveling at a steady speed of 10 and one tenth km/h. How long will it take the object to travel 4 and nine tenths km ? First round to the nearest integer to find the estimated answer. Then find the exact answer.

Estimated Answer=

Exact Answer=

Step-by-step explanation:

Steady speed of the object =10 and one tenth km/h =

Distance to be Covered=4 and nine tenths km = km

To the nearest integer,

Steady speed of the object = 10 km/hr

Distance=5km

=

The estimated answer is 1/2 hr.

Next, we determine the exact answer.

The exact time taken is

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
