The speed limit would be irrelevant, because the only practical vehicle which could travel at such speeds would be some sort of jet aircraft. You'd be traveling at a speed of 510 mph, which the only land vehicles capable of achieving such speeds are jet or rocket propelled vehicles designed specifically to challenge the land speed record.
speed limit 50 = 1 hour 521 divided by 50 = 10 hours and 21 minutes
usually 10 percent of the speed limit plus 2 mph.
No. You're still bound by the speed limit.
If someone runs 10 miles in 90 minutes their average speed is 6.67 mph
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.
7 miles every 10 minutes means 7 x 6 miles in an hour, so the speed is 42 mph.
10 miles.
It is 40 mph
You must maintain a pace of 18.75 mph to travel 10 miles in 32 minutes.
Your average speed is 10 miles per hour.
Your avarage speed would be 12 miles an hour.
Then your speed is 42 miles per hour
