Light travels at 186000 miles per second in vacuum.
2 hours
60 miles if he can sustain the rate.
The answer is 75 mph. If one travels at 45 mph for one mile, then in order to travel an average of 60 mph for the 2 miles, the rate must be 75 mph (60-45=15). Then add 15 to 60 to get the rate for the second mile. To check the answer add 75 and 45 and divide by 60 (the minutes in one hour) to get the distance (2 miles).
About one mile per hour.
