Step-by-step explanation:
jason ran the first 3 miles at 8mil/hr ie; so it took him 3/8 hrs to run 3 miles.
jason ran the final 2 miles at 6mil/hr ie; it took him 2/6 hrs to run 2 miles
the total time he took to run 5 miles will then be; 
if we divide distance/time we get his speed/velocity;
ie, 5/(17/24) = 6.47mil/hr
The expression:

gives the distance traveled by the aircraft in t hours, so, for t = 6:
A)He can cut 5 strips of of 7/10m.
7/10=0.7m
0.7*5=3.5m
3.5m of wire wil be used in cutting possible 7/10m pieces.
b)Leftover will be 0.6m.
4.1-3.5=0.6m
