Answer:

The circumference of the wheel can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is 18 inches, so the circumference is C = π * 18 = 56.52 inches.

To find out how many revolutions it takes to travel 1,700 meters, we first need to convert 1,700 meters to inches. Since 1 meter ≈ 39.3701 inches, 1,700 meters ≈ 66,929.17 inches.

Now we can divide the total distance in inches by the circumference of the wheel to find out how many revolutions it takes: 66,929.17 inches / 56.52 inches/revolution ≈ 1,184 revolutions.

Therefore, it will take approximately 1,184 revolutions of the wheel to travel 1,700 meters. This corresponds to option c.
