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
Algebraic expression 14 less than the quantity k times 6
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.
Jupiter has an average distance from the sun of 778.5 million km. That is not the distance from the earth. Sometimes it is less and sometimes it is greater, it moves. There is not a straight line distance it varies.Walking you cover an average of about 4 kilometres an hour. Divide that into the average distance. By the way, what are you going to walk on, breathe and eat.
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.
Speed is a scalar quantity with out direction, velocity is a vector quantity with a direction, The magnitude of a velocity, |V| is its speed. So all velocities have a speed, including a speed of zero.
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.
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.
donkeys is the clue
It will take less time.
