Total length of the board = 30 inch
Length of,
-- First piece = x
-- Second piece = 4x
-- Third piece = 5x
5x + 4x + x = 30
10x = 30
x = 3
Therefore, the lengths of:
-- First piece = 3 inch
-- Second piece = 4*3 = 12 inch
-- Third piece = 5*3 = 15 inch
Answer:80
Step-by-step explanation:
Volume of a cube = l^3, where l is the side length (note that the length, width and height in a cube are equal)
Volume of cube = 6^3 = 216 m^3
False because 6 is divisible by 2 and 3, but not 12
Time taken by Daniel to catch up with Frank is 4 minutes.
Step-by-step explanation:
The question is on relative speed; speed of a moving object with respect to another.
The two cars are travelling in the same direction at different speeds thus;
Relative speed = speed of Daniel - speed of Frank = 50-45= 5 mph
The time which the two meet = distance/ relative speed
Distance = 1/3 miles, which equals 0.33 miles
Time taken by Daniel to catch up with Frank is = 0.33/5 =0.066 hours = 4 minutes.
