Answer:
5
Step-by-step explanation:
The complex number 4 + 2i on the complex plane has coordinates (4,2) and the complex number 7 - 2i has coordinates (7,-2). Thus, the length of a segment in the complex plane with endpoints at 4 + 2i and 7 – 2i is

9:20 am
Lcm is 80 so 80 minutes after 8 am is 9:20
84 kilometers ... 1 hour
7 kilometers ... x hours = ?
If you would like to know how long does the pigeon take to fly 7 kilometers, you can calculate this using the following steps:
84 * x = 1 * 7
84 * x = 7 /84
x = 7/84
x = 1/12 hour
Result: A pigeon can fly 7 kilometers in 1/12 hour.
