The flow of water in a stream is 210 000 liters per hour. use scientific notation to calculate the amount of water that flows in a week (168 hours).

We know that in one hour, 210000 liters of water flow in the stream. To know the amount of water flowing in 168 hours, we will simply use cross multiplication as follows:

amount of water = (210000 x 168) / 1 = 35280000 liters

Now, we need to convert this number into a scientific notation:

Scientific notation means that we will eliminate the zeroes in the number and add a x10^number of zeroes

In 35280000 liters, we have 4 zeroes, therefore:

35280000 liters = 3528 x 10^4 liters = 3.528 x 10^7 liters
