Acompany produces coffee makers. the labor cost of assembling one coffee maker during the regular business hours is $2.75. if the work is done in overtime, the labor cost is $3.55 per unit. the company must produce 820 coffee makers this week, and does not want to spend more than $2479 in labor costs.
what is the smallest number of units that must be assembled during the regular hours?

450 is the final answer! : )

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.
