What is the speed of a dragster when it travels 60 feet in 1.7 seconds?
Assuming constant speed, you are supposed to divide the distance by the time.
What distance would be coveded by a train in 10 minutes if it travels a constant speed of 500 meters every 10 seconds?
30,000 metres or 30km
If an ladybug took 2.5 seconds to move from b to the line what is its constant speed during that time?
Not enough information. But basically, you need to measure or calculate the distance, and then divide the distance by the time.
What is the speed of a fall of 80 feet in 2.5 seconds?
average speed = (distance) / (time to cover the distance) = (80/2.5) = 32 ft/sec.We know that the speed was not constant during the 2.5 seconds. But with the information given,32 ft/sec average is the only thing we can calculate.
How does constant velocity differ from constant acceleration?
Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.
What is the shortest possible time in which car travels a distance of 1400m with a constant speed of 80ms?
If a car travels at a constant speed of 80m/s, then it covers the distance of 1,400m in exactly 17.5 seconds, no longer and no shorter. If the time is not 17.5 seconds, then either the distance was not 1,400m, or else the car's speed was not constant at 80m/s. Or both.
What is the answer of an elevator travels 310 feet in 10 seconds. At that speed how far can this elevator travel in 12 seconds Explain your reasoning.?
At 31 fps, the elevator will travel 372 feet in 12 seconds.
Does the total distance traveled divided by constant speed is an average speed?
No. If you divide a distance by a speed, you get a time, not a speed. For example, (meters) / (meters/second) = (seconds).
What is the velocity of a ball thrown 20 ft in 4 seconds?
In the case of constant velocity (or speed), velocity = distance / time.
What is the speed of a dragster when it travels 60 feet in 1.7 seconds?
Assuming constant speed, you are supposed to divide the distance by the time.
It takes an elevator 75 seconds to go 500 feet How fast is the elevator going?
About 4.5 miles per hour.
What distance would be covered in 12 minutes by a train that travels at a constant speed of 505 meters every 11 seconds?
33,055m or 33.055Km
How do you find constant speed?
You didn't specify what data is given. In general, for constant speed, the following formula is important (just use the definition of speed): speed = distance / time; or distance = speed x time. If distance is in km and time in hours, speed will be in km/hour; if distance is in meters and time in seconds, speed will be in meters/second.
How long does it take to get from one floor to the next in an elevator?
13 Seconds
What distance would be coveded by a train in 10 minutes if it travels a constant speed of 500 meters every 10 seconds?
30,000 metres or 30km
