I work that out as 4.87 seconds.
Data is insufficient. initial velocity is 0. final velocity is 30 mph. Need acceleration to use the formula v = u + at.
If a runner runs a mile in 4 minutes 30 seconds he is averaging 13.33 MPH over the total distance.
0.41 seconds.
About 20 seconds.

24.8 mph at that rate.

About 20 mph.
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).
About 7 minutes and 30 seconds.

It would take approximately 8 seconds to travel 492.8 feet at a speed of 30 mph.
35 feet at 30 mph requires about 0.8 seconds.
It is approx 6.102 mph.
