10miles
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.
Ten minutes.
33.333 miles.
The train traveled 180 miles.
330 miles
at what speed?
You traveled 15.5 miles.
About 12.75 miles at that rate of travel.
If you travel 30 km in 48 minutes, you travel an average of 7.5 km every 12 minutes. There are 5 12-minute segments in one hour, meaning you are travelling at an average rate of 37.5 km/h.
40 minutes is the time taken to travel 30 miles (48.3 kilometres) at an average speed of 45 miles per hour.
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.
You would travel 60 km in 30 minutes at 120 km/h
