Need a mathmatician!

If a vehicle can cover 7/10ths of a mile in 14 seconds. What is it's speed? :huh:

Ops I screwed up feet to meters

Let me start over hahahah

7/10 mile is 3696 feet

3696/14

264 feet per second

180 mph

Average speed of a traveling mile of 15 seconds would be 240 mph.

So from a stop to 7/10 mile would be around that. why share what you saw.

Assuming it is a constant rate of speed...

 

[midlife]

0.7 miles /14 seconds * 3600sec/1 hour = 180 mph.

 

[auron73mach1]

that's constant speed though...

 

[sm3570]

Really fast.

 

[69 Rustang]

Just a fast walk really . . . ;-)

 

[midlife]

If the 0.7 miles was reached from a standing start in 14 seconds, then the velocity at the end of the run was 360 miles/hour.

I leave it to the reader to prove.

Soo is this like a mid week fun question?

My brain hurts..

When I taught high school physics, one formula that all students had to remember was Velocity = Distance / Time. The answer to your question has been provided in previous posts. However, if the velocity is not constant from the beginning to the end of the 7/10ths of a mile, it becomes more complicated. Acceleration (change in velocity) enters the equation. Are you referring to constant or changing speed over the distance?
