Answer based on context:

Although Jerry Rice was named MVP, Montana had an MVP-worthy performance, completing 23 of 36 passes for a Super Bowl record 357 yards, throwing for 2 touchdowns, and gaining 14 rushing yards. Craig finished the game with 71 yards rushing, and 8 receptions for 101 receiving yards. He was the first running back in Super Bowl history to gain over 100 receiving yards. Taylor finished the game with a Super Bowl record 56 punt return yards. His 18.7 yards per return was also the highest average in Super Bowl history.  Linebacker Charles Haley had six tackles and two sacks. For Cincinnati, Jennings rushed one time for 3 yards, and gained 117 yards and a touchdown on 2 kickoff returns. Woods was the top rusher of the game with 79 yards. But Esiason was limited to just 11 out of 25 completions for 144 yards and no touchdowns, with 1 interception. Collinsworth (who retired after this game) was the Bengals top receiver of the game, but with just 3 catches for 40 yards.

How many yards per kickoff return, to one decimal place, did Jennings have on average?
58.5
