Using the word problem below, WRITE AN EQUATION to model the situation. Do NOT solve. A plumber charges a $40 service fee to come to your house. He also charges $50 for each hour that he works. The plumber charges you a total of $190. Use h for the number of hours.

50*h+40 = 190

Step-by-step explanation:

50*h+40 = 190 where

50h will give you how much you pay for the hours of work

40 is the flat fee that you add up to the total

lo.lll

step-by-step explanation:

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.
