Question

A foot bridge is 5 feet wide and is built with wood planks that are 6 inches wide. How many planks are needed to build the path?

Answer 1

To cover a 5-foot wide bridge with 6-inch wide planks, 10 planks are required. This is found by first converting 5 feet to inches (60 inches) and then dividing by the width of one plank.

Step-by-step explanation:

To determine how many wood planks are needed to cover the 5-foot width of a foot bridge using 6-inch wide planks, we first need to convert the width of the bridge into inches, since the width of the planks is given in inches. We know from unit conversion that 1 foot is equal to 12 inches.

Now, we calculate:

• 5 feet × 12 inches/foot = 60 inches (the total width of the bridge in inches)
• Next, divide the total width of the bridge by the width of one wood plank to find out how many planks are needed:
• 60 inches ÷ 6 inches/plank = 10 planks

Therefore, 10 wood planks are needed to build the path.

Answer 2

To build a 5-foot wide footbridge using 6-inch wide planks, 10 planks are needed after converting feet to inches and dividing the bridge width by the plank width.

Step-by-step explanation:

To determine how many 6-inch wide planks are needed to build a 5-foot wide footbridge, we first need to convert the width of the bridge to the same unit of measurement used for the plank width. We know that 1 foot equals 12 inches, so a 5-foot wide bridge is 5 x 12, which is 60 inches wide. Since each plank is 6 inches wide, we can simply divide the total width of the bridge by the width of one plank to find out how many planks are needed.

60 inches ÷ 6 inches = 10 planks.

Therefore, 10 planks are needed to build the footbridge.
