A recipe for bread calls for 414 cups of flour. Which expression gives the number of cups of flour needed if you want to make 312 batches of this recipe?

Number of flour (n) for one batch of recipe × batches of bread recipe (b)

129168 cups of flour

Step-by-step explanation:

According to the question, one recipe for bread requires 414 cups of flour.

I intend making 312 batches of this bread recipe.

Thus, in order to get the number of cups of flour needed to make this batch of bread recipe, we multipy the number of cups of flour needed for one bread recipe (n) by the number of batches of bread recipe about to be made (b).

In this case, n and b are 414 cups and 312 batches respectively.

Hence, we have; number of cups of flour needed for 312 batches of bread recipe=

414 × 312 = 129168

Thus, 129168 cups of flour will be needed to make 312 batches of bread recipe at 414 cups of flour per batch.

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
