Answer:total distance covered at the end of 12 hours would be 48 miles
Step-by-step explanation:
If you run for 4 hours at 8 miles an hour. It means that your speed while running is 8 miles an hour.
Distance = speed × time
Distance covered by running for 4 hours would be
4 × 8 = 32 miles
You walk 8 hours at 2 miles an hour. It means that your speed while walking is 2 miles an hour.
Distance covered by walking for 8 hours would be
2 × 8 = 16 miles
Distance that you would have covered after 12 hours would be
32 + 16 = = 48 miles
