Answer: The width of 10 lanes in the drawing will be 10 cm
Step-by-step explanation: If 3 cm = 15 ft, divide both sides by 3 to ro finf that 1 cm will represent 5 ft.
If each lane is 5 ft, the width on the drawing will be 1 cm for each lane.
10 lanes will be 10 cm.
And the 60 ft length will be 6 cm in the drawing.
