It will take 135/9 = 15 hours
135 ÷ 9 = 15 hours
The rate you should charge depends on how long it takes to get all of the trees planted. You can multiply how much you expect to make per hour by how long it takes to get an estimate of how much you should charge for the job.
The car is slowing down at a rate of 10 miles per hour for each hour it continues this rate.
the rate of the forest is falling is because our forest trees are geting knoked down badly
you overuse forests by cutting them down and not replanting trees. You do not overuse if the rate of use=to the rate of replenishment.
I believe they are and need to cut down the rate of cutting down forests.
They hunt down animals and cut down trees which destroys the ecosystems at an alarming rate.
If people replant the trees that they cut down, then the tree population will never run out. However if the rate at which the people are cutting down trees to the rate at which they are getting planted, they will soon be nonrenewable. Go plant a tree.
Long? It is 25 miles. Time? One hour.
About 1 hour and 22 minutes.
hour rate
A watt hour is a unit of energy, not time -so you cannot ask how 'long' it is. The time taken to consume a watt hour of energy depends upon the rate (i.e. the power) at which it is consumed, expressed in watts. A watt hour is defined as the amount of energy consumed, over a period of one hour, at the rate of one watt.
A train is traveling at 60 mph. If the rate of speed increases 4 mph each hour, how long will it be before the ship is traveling at a rate of 80 mph?
