Cassius walked 6 tenths of a 3.6-mile trail.
a. how many miles did cassius have left to hike?
b. cameron was 1.3 miles ahead of cassius. how many miles did cameron hike already?

distance left to hike by cassius is  1.44 miles  

Cameron hiked 3.5986 miles

Step-by-step explanation:

Cassius walked 6/10th of trail of 3.6 mile.

Part of the trail remaining = 1 - 6/10 = 4/10 = 2/5

Distance remaining will be  2/5 of 3.6 miles i.e 1.44 miles.

Hence distance left to hike by cassius is  1.44 miles  

b. Total distance by which Cameron was ahead of cassius =  1.3 miles.

Distance left to hike by Cameron = 1.44 miles - 1.3 miles = 0.0014 miles.

so, distance hiked by Cameron = 3.6 miles - 0.0014 miles = 3.5986 miles.

Cameron hiked 3.5986 miles.
