Ratio of height of the flag pole to the length of its shadow = 40:9.6 = 25:6 Ratio of height of the building to the length of its shadow = x:48 = 25:6 x/48 = 25/6 x = (48 x 25)/6 = 1200/6 = 200
Therefore, the height of the building is 200 feet.
To solve this problem we need to calculate the average speed at which the bus travelled. This is given by the distance travelled divided by the time that they took to get there. So we have:
You can multiply by 12 because to get rid of the fractions all terms should be divided by the LCM (ie the smallest multiple that is exactly divisible by 2, 4 and 3)
Multiples of 3 = 3, 6, 9, 12
Multiples of 4 = 4, 8, 12, 16
Multiples of 2 = 2, 4, 6, 8, 10, 12
Therefore the fractions should be multiplied by 12
