Administrators at a university will charge students $158 to attend a seminar. it costs $2160 to reserve a room, hire an instructor, and bring in the equipment. assume it costs $50 per student for the administrators to provide the course materials. how many students would have to register for the seminar for the university to break even?

$158s = Cost per student

$50s + $2160 = Cost of Uni

158s = 50s + 2160

-50s    -50s

108s = 2160

s = 20

At 20 students the university would break even.

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.
