The total distance covered by the plane is 80km + 100km = 180km, and the total time taken is 10 minutes + 20 minutes = 30 minutes. Therefore, the average speed of the plane is 180km / 30 minutes = 6 km per minute.
0.009 km is equivalent to 9 meters.
At 120 km/h, in 45 minutes (which is 0.75 hours), a vehicle would travel 120 km/h * 0.75 h = 90 km.
60 minutes
46 minutes have elapsed from 9:59 PM to 10:45 PM.
84 minutes
17000 x 9/60 = 2550 meters or 2.55 km
P waves travel at an average speed of about 6 km/s through the Earth's crust. In 9 minutes, they would travel approximately 9 x 60 x 6 = 3240 km.
The average speed of P-waves through the Earth is about 6-8 km/s. In 9 minutes, the P-waves would travel about 32,400-43,200 km.
Short answer: 45 minutes Explanation: We're going to use proportions to figure this out. We have a known proportion of 12 km per 60 minutes (one hour) which we'll represent as 12/60. We then have a similar proportion with 9 km of unknown time which we'll represent as 9/X. We know these two proportions are equal so we end up with the equation: 12/60 = 9/x Now we simplify: 12/60 = 9/X 12X = 9*60 12X = 540 X = 45 So now we know the proportion is 9 km per 45 minutes. We can also say that the runner can run 9km in 45 minutes.
.9 km 4 minutes
9 miles is equal to 14.484096 km Here is the formula for the conversion: 9 mi* 1.609344 km 1 mi = 14.484096 km
5 minutes
About 30 minutes.
12 km per hr
About 5.6 miles.
1 hour and 40 minutes is 100 minutes. 15 : 100 = 0.15 km/min. 0.15 x 60 = 9 km/hour. 9 : 3.6 = 2.5 m/s
