Depends what car it is.
Most cars can stop from 60 mph in about 100 feet or so. If the relationship is linear then a car should stop from 30 mph in about 50 feet.
That means that every hour, you move 30 miles. The actual distance travelled depends on the time travelled: d = st (distance = speed x time).
24 minutes.
1 hour and 30 minutes.
Depends what car it is.
time = distance / speed = 30 miles / (6 miles/hour) = 5 hours.
2,700 miles.
Stopping distance at 30mph = 23m

That means that every hour, you move 30 miles. The actual distance travelled depends on the time travelled: d = st (distance = speed x time).
You can go 7.5 miles driving at 15 miles per hour for 30 minutes. This is because 30 minutes is 1/2 of an hour, and 1/2 of 15 miles (the distance you travel in an hour) is 7.5 miles.
24 minutes.
They are inversely proportional, given that displacement is constant, as the equation shows : v = D/t This is logical. The faster an object moves, the less time it will take to travel a specific distance.
Stopping Distance = about 75 feet.
Distance = Speed*Time = 30 miles per hour * 7 minutes = 30 miles per hour * 7/60 hours = 7/2 miles
1 hour and 30 minutes.
