If you traveled 100 meters in 30 seconds, then you would be traveling at 3.333... meters per second, or 200 meters per minute, or 12 kilometers per hour (7.45 miles/hour).
If you traveled 42 miles that would be the equivalent of traveling 26.097582 KM
After 12 seconds, a car traveling at 87 miles per hour would have traveled approximately 1,520 feet. This can be calculated by first converting 87 miles per hour to feet per second, which is about 128 feet per second. Multiplying this by the number of seconds gives the distance traveled.
66 minutes
To calculate the speed in miles per hour, you can divide the distance traveled by the time taken. In this case, 169 miles divided by 3 hours and 30 seconds (converted to hours) would give you the speed in miles per hour.
If you you travel 3 miles, you would get 3 miles far.
approximately 38 mph
134/257 x 3600 seconds = 1877 seconds = 31minutes 17 seconds
1133 seconds
Simply use the formula v = d/t, where v is the speed, d is the distance traveled and t is time. Plugging it into the formula, we get v = d/t = 0.5/3 ~ 1.67 miles/second.
You would have traveled 80.4672 km.
speed 13 miles, 36 yards and 2 feet per hour
