20 miles at 16mph would take 1.25 hours. To complete the race in 2.5 hours, the final 30 miles must be completed in 1.25 hours ie 30/1.25 = 24mph
equality does not change signs inequalities do for greater than or less than equations
The answer depends on the rate of change of WHAT? The rate of change of the gas used? the rate of change of the gas left, the rate of change of the range that the vehicle will go? The question is too vague.
The slope of a distance-time graph gives the speed or velocity of the object. If the slope is steep, it indicates a higher speed, while a less steep slope indicates a slower speed. The slope is calculated by dividing the change in distance by the change in time.
6 is 30 less than 6 times itself. Suppose the number is x. Then 6 times itself is 6x. 30 less than that is 6x - 30 So x = 6x-30 so that 5x = 30 and then x = 6
If it's the average speed of [a,b] where a is less than b, both are on the x axis (time), and both are in the domain of x then the equation is(f(b)-f(a))/(b-a)where f(b) is the distance when time=b and f(a) is the distance when time=a(?)
97.7 kilometres (km) is a measure of distance. It makes no sense to try to convert that into a measure of speed: the distance could be traversed by electromagnetic radiation (light, for example) in less than a third of a millisecond, or more than a year for a slow snail.
If the object travels the same distance at a higher speed, the time it takes to travel the distance will decrease. This is because time is inversely proportional to speed when distance is constant. So, increasing the speed will result in less time taken to cover the same distance.
It is purely a distance. If you say 5 miles per hour that is called a velocity, or speed. So the distance is velocity times time. If the velocity changes during the time interval, the distance is the sum of all the tiny distances multiplied by the velocity at each interval. If the path is curved, that's still OK, but the final distance from the start point will be less, and could even be zero.
When an object accelerates it can change its speed or direction of motion. When it accelerates without changing its direction of motion, it can cover any distance in less time.
Time affects the distance traveled by an object in motion through the formula distance = speed x time. The longer the time, the greater the distance traveled if the speed remains constant. Conversely, if the time is decreased, the distance traveled will also be less if the speed remains constant.
It depends on the aircraft. The average speed of a Cessna at touchdown is lower than the average speed of an Airbus 380. 200 KM average or it may be less if pilot is expertise.
Less than . :) Karls(:
If the distance of travel remains constant in every case, then the time required to cover the distance is inversely proportional to the speed of the particle. T = (constant) divided by (speed) or: (Time) x (Speed) = A constant, if the distance under consideration doesn't change. Note: This expression is a good approximation at everyday speeds. It becomes less accurate at speeds where relativistic effects become significant.
donkeys is the clue
