Answer: After 4.55 hours the ships will be nearest to each other, and this distance would be 54.54 km.
Step-by-step explanation:
Since we have given that
Distance between ship A and ship B = 100 km
Speed at which Ship A is sailing west = 12 km/hr
Speed at which Ship B is sailing south = 10 km/hr
Since they are sailing opposite to each other, so their relative speed would be
So, Time taken is given by
Distance would be
Hence, After 4.55 hours the ships will be nearest to each other, and this distance would be 54.54 km.

Answer:
5√3 or
8.66 to the nearest hundred.
Step-by-step explanation:
Length of each line of the triangle = 30/3 = 10.
The altitude, side and 1/2 base make a right triangle.
So by Pythagoras:
10^2 = 5^2 + h^2 where h = altitude.
h^2 = 100 - 25 = 75
h = √75 = 5√3.
Answer:
263.76 inch
Step-by-step explanation:
Diameter of the bicycle wheel = 42 inch
Hence radius of the bicycle wheel =
inch
The wheel rolls through an angle of 720 degrees.
In 720 degrees the wheel covers 2 revolutions.
Distance covered by the wheel in 1 revolution =
inch
So in 2 revolutions, the distance covered by the wheel will be
This is equal to 263.76 inch.
