The UK highway code uses the formula:
distance = thinking_distance + braking_distance
= speed + speed2 ÷ 20
with speed in mph and distance in feet. This is for a normal, unaffected, person in a vehicle with good brakes and tyres, and dry conditions.
So for 55 mph, the stopping distance would be:
distance = 55 + 552 ÷ 20
= 55 + 151.25
= 206.25 ft
≈ 63m
If the driver has different than "normal" reaction times and the road is slippery (due to rain, snow, dust(!), etc), then the stopping distance will vary, usually longer, the Highway Code suggesting allow double at least.
However, as far as I know the Highway Code has not been updated for the vast improvements in braking, etc since it was first published; also, the same stopping distances are considered for a (less than) 1 tonne family car and fully laden 23 tonne coach.
Fun fact: the stopping distance (given above) for 70 mph (the legal limit for a car on the UK motorways) is 315 ft or 96m; this can easily be visualised as the marker posts to the nearest emergency phone are 100m apart - approximately the stopping distance in an emergency!
633600 feet per hour
60 miles per hour = 316800 feet per hour.
1 mile per hour = 22/15 = 1.4666... feet per second (rounded, repeating)The following are exact numbers:-- 15 miles per hour = 22 feet per second-- 30 miles per hour = 44 feet per second-- 60 miles per hour = 88 feet per second-- 90 miles per hour = 132 feet per second-- 120 miles per hour = 176 feet per second
If you drive for an hour, you have driven 45 miles. If you have driven for a longer or shorter time, you have driven more or less, respectively. You have to specify the amount of time to get the answer.
There are 5280 feet in one mile. Therefore, 400 miles per hour is equal to 400 x 5280 = 2112000 feet per hour.
In 1 hour, a car driving at 55 miles per hour will travel 80.67 feet per second. So in 1 second, it would travel around 80.67 feet.
A scalar is a magnitude only (...I am driving at 60 miles per hour), while a vector is a magnitude and direction (...I am driving at 60 miles per hour, heading east).
The shortest route is 94.4 miles which is an hour and 46 miles minutes while driving.
60 miles
To convert feet to miles, divide by 5280 (1 mile = 5280 feet). To convert hours to miles per hour, divide distance in miles by time in hours. Thus, to convert 30000 feet to miles per hour, first convert feet to miles (30000/5280), then divide by the number of hours to get miles per hour.
1200 feet per second is equivalent to approximately 818 miles per hour.
That depends on the speed at which you are driving. For example, if you are driving 52.6 miles/hour, it would take an hour to drive that far. If you are driving 23.8 miles/hour, it would take two hours to drive that far.
One hour.
To convert feet per hour to miles per hour, you need to consider that 1 mile is equal to 5280 feet. Therefore, to convert feet per hour to miles per hour, you would divide the feet per hour value by 5280. This will give you the equivalent value in miles per hour. For example, if you have a speed of 5280 feet per hour, it would be equal to 1 mile per hour.
A car driving 50 miles per hour travels 264,000 feet in one hour or 4,400 feet per minute or 73.3 feet per second. 50 x 5,280 feet (per mile)= 264,000 divided by 60 = 4,400 divided by 60 = 73.3
6 hours 20 minutes.
184 feet per second is 125.45 miles per hour.
