125 hours.
Although most of the time power is measured in Watts, it can also be expressed as Js-1. So in your question, you are given the amount of joules and the time in hours. First, convert 5 hours to seconds. There are 60 mins in an hour and 60 seconds in a minute. So that's going to be 5x60x60 = 18000 seconds Now all you do in divide the number of joules by the number of seconds to work out the power. So that's 7500/18000 = 0.41666666666... approximately, 0.42Js-1(2dp) and thats the same as 0.42W (2dp)
3% of 7500 = 3% * 7500 = 0.03 * 7500 = 225
67% of 7500 = 67% * 7500 = 0.67 * 7500 = 5025

60 minutes = 1 hour so 7500 minutes = 7500/60 = 125 hours. Simple!
125 hours.
seconds I assume. 7500/60 is 125 mins
7500 meters per 10 seconds = 750 meters per second = 2,700 km per hour. That's a fast dog.

The distance a beam of light would travel in 7500 seconds can be calculated by multiplying the speed of light by the time traveled: 3.00 x 10^8 m/s * 7500 s = 2.25 x 10^12 meters. The beam of light would travel 2.25 trillion meters in 7500 seconds.
