The blue Lake Trail is 11 3/8 miles Long Gemma has hiked 2 1/2 miles each hour for three hours how far is she from the end of the trail

Gemma is 3 7/8 miles from the end of trail.

Step-by-step explanation:

Given that,

length of blue lake trail = 11 3/8miles

time Gemma has hiked = 3 hours

distance Gemma have travelled in a hour = 2 1/2

Total distance Gemma have travelled = 2 1/2 * 3

= (2*2+1) / 2 * 3

= (5/2) * 3

= 15/2

= 7 1/2miles

Distance Gemma is from the end of trail (11 3/8) - (7 1/2)

= 91/8 - 15/2

= 91/8 - 15*4/2*4

= 91/8 - 60/8

= (91-60) / 8

= 31/8 miles

= 3 7/8 miles
