Answer:
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
