Question

Timothy wants to know how far his math class is from the orange tree across the street from the school. His feet are ideal feet (meaning they are 1 foot long. 1 foot is 12 inches). Timothy finds that the orange tree is 159 feet from the door of the math classroom. He wants to know that distance in kilometers (km).a. Convert from feet to inches (1 ft =12 in)b. Convert from inches to centimeters (1 in =2.54c. Conver from centimeters to meters (1m = 100cm)d. Convert from meters to kilometers (1km=1000m)

Answer 1

a) 1 foot = 12 inches

159 feet = 159 x 12 = 1908

The distance in inches is 1908 inches

b) 1 inch = 2.54 cm

1908 inches = 1908 x 2.54 = 4846.32

The distance in centimeters is 4846.32 cm

c) 100 cm = 1 m

4846.32 cm = 4846.32/100 = 48.4632

The distance in meters is 48.4632 m

d) 1000m = 1 km

48.4632 m = 48.4632/1000 = 0.0484632

The distance in kilometers is 0.0484632 km
