The relationship between the amount of money Steven charges and the time he spends babysitting is proportional because the hourly rate remains constant.
A proportional relationship between two variables means that the ratio of the two variables is constant. In other words, if the independent variable (time in this case) increases, the dependent variable (the amount of money Steven charges) will increase proportionally.
In this situation, we can see that the relationship between the amount of money Steven charges and the time he spends babysitting is proportional because the rate of change between the two variables is constant.
For example, Steven charges $31.25 for 5 hours, so his hourly rate is $31.25/5 = $6.25/hour.
And he charges $50 for 8 hours, so his hourly rate is $50/8 = $6.25/hour.
Since the hourly rate remains constant, the relationship between the amount of money Steven charges and the time he spends babysitting is proportional.

Multiply 125.5 miles by 1.61 to get total kilometers:
125.5 x 1.61 = 202.055 kilometers total.
Divide 150 minutes by 60 to get total hours:
150/ 60 = 2.5 hours.
Now Divide total kilometers by total hours to get kilometers per hour:
202.055 kilometers / 2.5 hours = 80.822 kilometers per hour.
Round the answer as needed.
Answer:
80.822 km/hour
Step-by-step explanation:
A train travels in 150 minutes = 125.5 miles.
First we will convert 125.5 miles to kilometers
1 mile = 1.61 kilometers
125.5 miles = 125.5 × 1.61
= 202.055 kilometers
1 hour = 60 minutes
150 minutes =
= 2.5 hours
Hence the train travels 202.055 kilometers in 2.5 hours.
Therefore, The speed of the train in one hour =
= 80.822 km/hour
The trains speed is 80.822 km/hour.
The answer is:
To solve the problem, remember to set your calculator in "degree mode"
So, we are given that the angle A is equal to 68°
So, we have that:
Hence, we have that:
