Terry is making 3 hat and scarf sets .Ech scarfs requires 3 yards of material and eche hat required 30 inches how many feet of material dose he need for all 3 hats set

34.5 feet of material for 3 hat and scarf sets.

Step-by-step explanation:

First, we need to convert all measurements to the same unit: foot. (Because the answer is requested in foot)

1 yard is equal to 3 feet, and 1 inch is equal to 0.08333 feet.

3 yards are equal to 9 feet, and 30 inches are equal to 2.5 feet.

We need 3 sets of hat and scarf, so this means that we need 3 hats and 3 scarfs.

One scarf needs 9 feet of material, so 3 scarfs need 27 feet.

One hat needs 2.5 feet of material, so 3 hats need 7.5 feet.

In total, 3 scarfs and 3 hats need 27+7.5=34.5 feet of material.

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.
