A marathon is 26.2 miles, so if you run it in 1.5 hours, your speed is 17.47 miles per hour.
Something to note: The record time for running a marathon is 2:02:57 (set by Dennis Kimetto in 2014 in Berlin).
35 miles
245 miles.
It's 25 miles per half-hour, and it's also 50 miles per hour.
30 minutes.
162.5 miles
Well, 30 minutes is exactly half of an hour so you would cover half of the 40 miles = 20 miles
Answer: 12 km/h = 7.45645 mph
To determine how many miles are in an hour and a half, you need to know the speed at which you're traveling. For example, if you're driving at 60 miles per hour, in an hour and a half (1.5 hours), you would cover 90 miles (60 miles/hour × 1.5 hours). If you travel at a different speed, simply multiply that speed by 1.5 to find the distance.
5 and a half hours
127.38109440865345 Miles per Hour
216,000 miles per hour.
12 km/hr is roughly 7 and a half miles an hour (7.456 mph).
