Kimo's car needed work. the mechanic charged him $140 for parts plus $48 per hour for labor. if the bill totaled $260, how many hours of labor were required?

Hi!

We will find the hours of labor, x, like this:

140 + 48 * x = 260

48 * x = 260 - 140

48 * x = 120

x = 120/48

x = 2,5 hours of labor were required

Hope this helps!

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.
