35 MPH equals 51.33 feet per second. So it would take 0.974 seconds to go exactly 50 feet at exactly 35 MPH.
In reality, you need to be concerned with the accuracy of your original measurements, and not perform calculations to a level of precision that isn't appropriate to the precision of your measurements. Your car's speedometer probably isn't accurate to a half mile per hour, so when your speedometer says "35", you're probably going somewhere between 33 and 37 MPH.
Saying that it would take "about one second" is going to be close enough to the right answer.
You are traveling 70.18 feet every 1.1 seconds at 43.5 mph
125840 feet in 22 minutes
There are 5,280 feet in a mile. Therefore, at 7 miles an hour, you would be traveling at 7 * 5,280 = 36,960 feet per hour. Now convert hours to minutes: 36,960 / 60 = 616 feet per minute. Now convert minutes to seconds: 616 / 60 = 10.27 feet per second.
5.25
It will travel ten feet.
You are traveling 70.18 feet every 1.1 seconds at 43.5 mph
1 second if you are traveling 15 feet.
146.66 feet every 10 seconds at 10 mph.
2.27 seconds to go 100 feet @30mph
If it takes 78 seconds to go 55 feet you are traveling at 0.48 miles per hour.
At 100 mph, an object is traveling about 146.67 feet every second. Therefore, to travel 60 feet at 100 mph would require about 0.41 seconds.
Traveling at 60 miles per hour, you would cover 88 feet in 6 seconds.
Roughly 3 and a half seconds. For every one mile and hour, a car travels 1.5 feet a second
5 minutes is 300 seconds so 9000 feet
At 55 mph you are moving at about 80.667 feet every second. So, in 11 seconds, you would travel about 887.337 feet. (80.667 x 11 = 887.337)
To convert speed from miles per hour to feet per second, you need to multiply by 1.46667. So at 25 miles per hour, you are traveling at approximately 36.67 feet per second. To travel 100 feet at this speed, it would take around 2.73 seconds.
They are traveling at 4.9 mph
