6.8 miles
Step-by-step explanation:
We can apply the formula :
⇒ Mean distance per diver = Total distance covered / No. of divers
=============================================================
Given :
⇒ Number of divers = 28
⇒ Total distance travelled = 190.4 miles
===========================================================
Solving :
⇒ Mean distance = 190.4 miles / 28
⇒ Mean distance = 6.8 miles
