Answer:
The rate of change in distance between the spy and the rocket is 10.8 km/min,
or about 180 m/sec.
Step-by-step explanation:
At "Time=0" the rocket is 6km from the spy.
The rocket travels vertically 8km in about 0.37 minutes, calculated by 8km÷21.6km/min.
At that point, the rocket is 10 km from the spy., calculated by 6²+8²=10²
The difference is 4 kiilometers over 0.37minutes, about 22.2 seconds
Divide Distance by Time to get Rate:
4km/0.37min = 10.8 km/min
That is about 180 meters per second.
I believe it's 4. 1/2 = 1/4
so, 1/2 + 1/2 + 1/2 + 1/2 would be 4/4...
Answer: 53 inches
Step-by-step explanation:
so to figure this out..
1. split the shape. there will be a 6 by 8 rectangle and a Height of 2 inches and the length of 5 inch triangle.
2.then find the area of 6 * 8 equals 48
3.Then find the area of the triangle. 5 * 2 equals 10. then Divide 10 / 2 your answer will be 5
4.Then add 48 and 5 together your answer will be 53
Use a ruler to solve it there is directions there for a reason
Answer: 7.5 minutes (7 min 30 sec)
Step-by-step explanation: If it takes it 3 minutes to travel 2 km, it would take it 1.5 minutes to travel 1 km. So, 1.5 * 5 = 7.5, meaning it would take it 7.5 min to travel 5 km.
