Answer:
(a) 680 km
(b) 680000 m
Step-by-step explanation:
(a) Distance run by hunter every day = 6.8 km
Total number of days under consideration = 100
So the total distance covered by the hunter =
= 680 km
The hunter ran 680 km in the last 100 days.
(b) Converting this value to meters:
1 km = 1000 m
=> 680 km = 680 * 1000 m
= 680000 m
The equivalent distance run by the hunter when converted to meters is 680000 meters.
