A triathlon course includes a 400m swim, a 40.1km bike ride, and a 12.2km run what is the total length of the course

A. 42km

B. 52.7km

C. 31km

D. 33.4km

Convert the meter distance to KM so thaey are all the same measurement:

1 meter = 0.001 km

400 m x 0.001 m/km = 0.4 km

Now add all three distances:

Total distance = 0.4 + 40.1 + 12.2 = 52.7 km.

The answer is B.
