Answer:
10 hours
Step-by-step explanation:
The rate x time of the first day + the rate x time of the second day equal the distance of 180 miles.

10t + 8t = 180
18t = 180
t = 10
Answer:
Step-by-step explanation:
1) radius = 70 m
Perimeter of a circle = 2 * radius * 3.14 = 70 * 2 * 3.14 = 439,6 m
Total perimeter = 439.6 + (100 * 2) = 439,6 + 200 = 639.6 m
2) perimeter of a semi circle = radius * 22/7 = 7 * 22/7 = 22 cm
