A bathtub, in the shape of a rectangular prism, measures 8 feet long by 3 feet wide by 2 feet deep. If the tub fills at a rate of 5 cubic feet per minute, then how many minutes will it take to fill the bathtub?

Step-by-step explanation:

The volume of the tub is 5 ft  * 3 ft * 1.5 ft  = 22.5 ft^3

Three-fourths full makes the amount  (3/4)(22.5 ft^3) = 16.875 ft^3

Draining at 1 ft^3 / min, it takes almost 17 minutes  (16 7/8

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.
