Answer:
1.283 seconds
Explanation:
Given,
Distance between the earth and the moon = 3.85 × 10^8 meters (m)
Speed of the radio waves in space = 3 × 10^8 meters/second (m/sec)
As we know that,
Speed = 
Time = 
Time = 
Therefore, Time = 1.283 seconds.
Thus, the time it took for the voice of Neil Arm Strong to reach the earth via radio waves is 1.283 seconds.
The (east) longitudes are as follows:
kanpur: 80° 19' 48"
jaffna: 80° 0' 36"
chennai: 80° 16' 12"
colombo: 79° 51'
mumbai: 72° 49' 12"
The city farthest from 80°E is Mumbai, India.
_____
It is about 7° farther away than the next closest city, Colombo.
