There are 60 seconds in a minute, so to find the number of seconds in 30 minutes, you would multiply 60 by 30. This equals 1800 seconds. Therefore, there are 1800 seconds in 30 minutes.

300 feet in 10 seconds = 30 feet per second. 1 mile = 5280 feet. 5280 feet at 30 ft/sec = 5280/30 = 176 seconds = 2 minutes 56 seconds. Except that he will not be able to keep up that pace.
I work that out as 4.87 seconds.
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.
In 2 seconds at 30 mph (44 ft/s), the distance travelled would be 88 feet. This is calculated by multiplying the speed in feet per second (44 ft/s) by the time in seconds (2 seconds).
30 times as much, since a minute has 60 seconds.
About 20 mph.
It would take approximately 8 seconds to travel 492.8 feet at a speed of 30 mph.
Roughly 3 and a half seconds. For every one mile and hour, a car travels 1.5 feet a second
About 1.6 miles per hour.
