Answer:
Step-by-step explanation:
In order to round the given decimal numbers to the nearest whole number, you need to observe the first digit after the decimal point:
- If this is 5 or greater than 5, then you must round the number up and remove the decimal part.
- If this is less than 5, then you must round the number dowm and remove the decimal part.
Then, you get that:
Given parameters:
Distance traveled = 1778miles
Average speed = 61.7 miles per hour
Unknown:
Time taken for the travel = ?
Speed is a physical quantity. It is the rate of change of distance with time.
It can be mathematically expressed as;
Speed =
The unknown here is the time taken;
Substitute the parameters and solve for it;
61.7 =
time taken = = 28.8hrs
The time taken is 28.8hrs

Answer:
Length of string = 30.52 m (Approx)
Step-by-step explanation:
Given:
Angle of elevation = 55°
Height of kite = 25 m
Find:
Length of string
Computation:
Sin 55 = Height of kite / Length of string
0.8191 = 25 / Length of string
Length of string = 25 / 0.8191
Length of string = 30.52 m (Approx)
