Question

A factory can build 15 cars every hour. If at a certain time of day , they have already built 9 cars,how many cars in total will they have built 5 hours from now?

Answer 1

Answer:

They would have built 84 cars

Step-by-step explanation:

From the question, they have already built 9 cars

Now, the hourly production rate is 15 cars per hour;

So therefore, in 5 hours, total that would have been built excluding the initial 9 will be;

15 * 5 = 75 cars

Now, let us add the initial 9

we have this as 9 + 75 = 84 cars
