36523.8 m = 36.5238 km

Explanation:

Start by converting all units to SI units:

30.9 minutes = 60*30.9 = 1854 seconds

Let t_(t otal) denote time, so t_(t otal) = 1854 s

Let s_(avg) represent average speed, so s_(avg) = 19.7m/s

Let d_(t otal) represent total distance traveled, in m

s_(avg) = d_(t otal)/t_(t otal)

Rearranging,
d_(t otal) = s_(avg) * t_(t otal)

d_(t otal) = 19.7m/cancel(s) * 1854cancel(s) = 36523.8 m = 36.5238 km
