Given that a factory produces 7500 cans of juice in five hours, what is its average rate of production in cans per hour?

We are told in the question that the factory produces 7500 cans in five hours. We need to calculate the average rate of production in cans per hour. Assuming that cans are produced at the same rate per hour, we need to calculate how many cans will be produced in one hour. Five divided by five is equal to one. This means that we need to divide 7500 by five. We can do this using the short-division bus stop method.

Seven divided by five is equal to one remainder two. So we carry the two to the hundreds column. 25 divided by five is equal to five. As zero divided by five is equal to zero, we have a zero in the tens and ones column. 7500 divided by five is 1500.

We can therefore say that, on average, the factory produces 1500 cans per hour. If we were given different figures, the average rate can be calculated by dividing the total number of cans by the total number of hours.
