Hunter is filling a 3.5-gallon
bucket to water plants at a faucet that flows at a rate
of 1.75 gallons a minute. if he were to add a hose
that flows at a rate of 1.45 gallons per minute, how
many minutes would it take him to fill the bucket?
round to the nearest tenth.

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.
