It would take approximately 8 seconds to travel 492.8 feet at a speed of 30 mph.
To calculate the speed, you would divide the distance traveled by the time it took to travel that distance. In this case, traveling 5000 feet in 30 seconds means you are traveling at a speed of 166.67 feet per second.
30 miles per hour is 44 feet per second.
To determine how many miles per hour you can mow a lawn of 100 feet in 30 seconds, first convert feet to miles (1 mile = 5280 feet), then convert seconds to hours (1 hour = 3600 seconds). After these conversions, you can calculate the speed in miles per hour.
mph means miles per hour just record how long it takes to go one mile. If you walk for a mile and it takes 30 minutes then your speed for that mile was 2 mph. If you walk for a mile and it takes 15 minutes then your speed for that mile was 4 mph. ... lets do a crazy one... If you walk for a mile and it takes 23 minutes and 30 seconds then your speed for that mile was 2.55 mph. The math is simple. If your time is in minutes just take 60 minutes and divide into that the total amount of minutes you took to walk a mile. So the calculations for the three examples would be... 60 / 30 = 2 mph 60 / 15 = 4 mph 60 / 23.5 = 2.55 mph (23 minutes and 30 seconds is the same as 23 and a half minutes)
I work that out as 4.87 seconds.

About 20 mph.
35 feet at 30 mph requires about 0.8 seconds.

When traveling 30-mph, the braking distance is 45-feet, and the total stopping distance is 75-feet. This is the length of a semi-truck and trailer.
