42.86 miles per hour.

158.8mph for 343 miles in 2hours and 16 min
If you went at a speed of a mile a minute, or 60 mph, you would travel 25 miles in 25 minutes. For 10 miles in this time you only have to travel at 2/5 of that speed, or 24 mph.
You are traveling 0.22km per minute or you need 4.5 minutes to travel one km
The minimum speed you need to go to travel 1 mile in 30 minutes is .5 miles per hour, or 44 feet per second. actually to travel one mile in 60 minutes (one mile per hour),you walk...well,one mile per hour.Therefore to walk the same distance in half the time,you have to double the speed,in this case,2 miles per hour.
If my calculations are right you need to travel 20 miles per hour to reach ten miles in thirty minutes.

If you went at a speed of a mile a minute, or 60 mph, you would travel 25 miles in 25 minutes. For 10 miles in this time you only have to travel at 2/5 of that speed, or 24 mph.
6.29*60/25 = 15.096 mph
3 miles an hour
You will need to travel at an average of 25 miles ÷ 2 hours = 121/2 mph.
Assuming you maintain a constant speed throughout your run, you will need to be running the mile at a pace of 8:00 minutes. So, by dividing 60 minutes by your time of 8 minutes you get 7.5. This means you will have to run a pace of 7.5 mph for 12 minutes to travel 1.5 miles.
32 mph
A speed of 90 miles per 75 minutes or 72 miles per 60 minutes. If you must have it in more conventional form, then 72 mph.
You would need to drive 2.85 miles per minute which is 171.4 mph.
