Answer:

Distance remaining (out of total 81 miles) after travelling 9 hours at speed 3 miles per hour = 54 miles

Step-by-step explanation:

Lets suppose -

Time = 9 hours

Total Distance = 81 miles

Speed = 3 miles per hour

  • Distance = Speed x Time

Distance covered in 9 hours = 3 x 9 = 27 miles

  • Distance remaining = Total distance - distance covered

=  81 - 27 = 54 miles
