Explanation:

To find out how many inches are in a 5k race, we need to perform a few conversions. A 5k race is 5 kilometers long, and to convert this to inches, we start by converting kilometers to meters, then meters to centimeters, and finally centimeters to inches, using the given conversion factors.

First, convert kilometers to meters.

5 km = 5 × 1000 m = 5000 m

Next, convert meters to centimeters.

5000 m = 5000 × 100 cm = 500000 cm

Finally, convert centimeters to inches.

500000 cm × (1 inch / 2.54 cm) = 196850 inches approximately.
