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.
It can travel 45km in one hour, and 40 minutes is 2/3 of an hour, so it can travel 2/3 of 45km, which is 30km.
To find the average speed, you divide the distance by the time taken. In this case, the distance is 3 kilometers and the time is 15 minutes. First, convert 15 minutes into hours, which is 0.25 hours. Therefore, the average speed is ( \frac{3 \text{ km}}{0.25 \text{ hours}} = 12 \text{ km/h} ).
2 hours 50 minutes.
4.6ms
492km/h 08/60= .13333 .13333/64= 492.3km/h
Your average speed is 44.3 miles per hour.
60 kph
46.64788km/h
1376 minutes.
16 km is not a speed (average or otherwise), it is a distance. It is therefore impossible to answer this question.
180 mph
540 kilometres per hour.

It can travel 45km in one hour, and 40 minutes is 2/3 of an hour, so it can travel 2/3 of 45km, which is 30km.
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.
To find the average speed, you divide the distance by the time taken. In this case, the distance is 3 kilometers and the time is 15 minutes. First, convert 15 minutes into hours, which is 0.25 hours. Therefore, the average speed is ( \frac{3 \text{ km}}{0.25 \text{ hours}} = 12 \text{ km/h} ).
