the distance in miles a family has traveled so far on their trip can be modeled by the equation y=0.6x - 75, where x is the number of minutes of driving today. how many minutes has the family been traveling today when they have traveled 201 miles

Step-by-step explanation:

y = 0.6 x -75

201=0.6x-75

0.6x=276

x= 276/.6

=460

So, travelled for 460 minutes.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

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.
