On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours. Find both the miles driven per hour and the hours driven per mil
amid [387]

Miles driven per hour is 60 miles per hour

Hours driven per mile is 0.01667 hours per mile

<em><u>Solution:</u></em>

Given that,

On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours

Therefore,

Miles driven = 210 miles

Time\ taken = 3\frac{1}{2}\ hour = \frac{7}{2} = 3.5\ hour

To find: miles driven per hour and the hours driven per mile

<h3><u>Miles driven per hour</u></h3>

\frac{miles}{hour} = \frac{210}{3.5}\\\\\frac{miles}{hour} = 60\ miles\ per\ hour

<h3><u>Hours driven per mile</u></h3>

\frac{hours}{miles} = \frac{3.5}{210}\\\\\frac{hours}{miles} = 0.01667\ hours\ per\ miles

Thus both the miles driven per hour and the hours driven per mile are found

For the fourth week of April, Kevin Nelson worked 46 hours. Kevin earns $17.90 an hour. His employer pays overtime for all hours
Dominik [7]

Answer:

Explanation:

From the information given,

Total number of hours worked = 46

Hourly rate = $17.90

Thus,

amount earned for the first 40 hours = 40 x 17.9 = 716

Overtime = 46 - 40 = 6

overtime rate = 1.5 times the hourly rate = 1.5 x 17.9 = 26.85

Amount earned for overtime = 26.85 x 6 = 161.1

Total amount earned = 716 + 161.1

Total amount earned = $877.1
