I need this by tmr pl A group of students in a health class track their daily steps to find out how far they walk. The students use different smartphone apps to track their distances. Some apps display distances using decimals, while others use fractions. The table shows the total distances walked by the group of students so far. The battery of Shauna's phone ran out of power before her distance could be recorded.

Distance Walked (miles):
Mariko- 12.6
Clyde- 12 5/6
Shauna- 12 5/6
Jin- 12 7/8
Todd- 12.8

What is the total distance the group of students walked, rounded to the nearest tenth?
