840 feet/40 seconds = 21 feet per second.840 feet/40 seconds = 21 feet per second.840 feet/40 seconds = 21 feet per second.840 feet/40 seconds = 21 feet per second.
The answer depends on what gas the balloon contains, its initial velocity and the forces - gravity, buoyancy, cross-wind - acting on it.
Impossible to answer ! Feet is a measurement of distance - seconds is a measurement of time (or angles)
A mile has 5,280 feet. Therefore, 25 miles is equal to 5,280 x 25 = 132,000 feet. That is the distance covered in 1 hour at 25 mph. To cover 72 feet would require 72/132,000 = 5.4545454545454545454545454545455e-4 of one hour. In seconds, this is 5.4545454545454545454545454545455e-4 * 3600 = 1.9636363636363636363636363636364 seconds. 3600 is the number of seconds in one hour. Hope this helps. Tyro
100 feet in 10 seconds gives an average speed of 10 feet per second.
It is generally not allowed to pass or cross the center line within 100 feet of an intersection. This is to ensure safety and prevent collisions with vehicles entering or exiting the intersection.
Because then the point of intersection would have to be two different altitudes like if a 290 feet and 300 feet countor lines cross it would have to be both 290 and 300 feet altitude at the same time which is impossible
1 mile in 45 seconds is 80 mph. There are 60 seconds in a minute and 60 minutes in an hour; 60 * 60 = 3,600 seconds in an hour. 3,600 / 45 seconds = 80. And to cross-check: 80 mph * 5,280 feet in a mile = 422,400 feet per hour / 60 = 7,040 feet per minute / 60 = 117 1/3 feet per second * 45 seconds = 5,280 feet in 45 seconds.
