Easy - 20 minutes is one-third of an hour, and the bus traveled 30km. Multiply that 30km by three and that gives the total distance it would travel in one hour. Answer is an average speed of 90kmh.
An hour is 60 minutes, so the cyclist would travel 2.4 x 6=14.4 mph (miles per hour)
The number of miles you would travel in 8 minutes would depend on the speed you are traveling. At 60 miles per hour, you would travel 8 miles in 8 minutes.
In order to calculate how many minutes it would take someone to travel 5 kilometers you need to know the speed the person is traveling at. For example if the person is traveling at a speed of 60 kilometers an hour it would take them 5 minutes to travel 5 kilometers.
That of course would depend on your speed and form of transport.
20 minutes
If you traveled at the speed of light (a current impossibility), you would travel from Earth to the Sun in an average of 8 minutes. Or would you? I suspect that you would burn up well before the 8 minutes were up.

40 minutes. 24 miles is two thirds of 36. Two thirds of an hour is 40 minutes.
Either acceleration, average speed, direction, or instantaneous speed.
An hour is 60 minutes, so the cyclist would travel 2.4 x 6=14.4 mph (miles per hour)
8 minutes
20 mph. At that speed, in one hour you would travel 20 miles. After half an hour of traveling at that speed, you would have gone 10 miles.
The number of miles you would travel in 8 minutes would depend on the speed you are traveling. At 60 miles per hour, you would travel 8 miles in 8 minutes.
It would take 21.70/18.88 = 1.15 hours = 1 hour 9 minutes, approx.
In order to calculate how many minutes it would take someone to travel 5 kilometers you need to know the speed the person is traveling at. For example if the person is traveling at a speed of 60 kilometers an hour it would take them 5 minutes to travel 5 kilometers.
Light travels at a speed of about 186,282 miles per second. The time it takes for light to travel to Jupiter depends on the distance between Earth and Jupiter, which varies as they orbit the sun. On average, light takes about 33 minutes to travel from Earth to Jupiter when they are at their closest approach.
