5. A motorist leaves Derby at 10:55 and arrives in Leicester 1 14 hours later. The
distance from Leicester to Derby is 50 miles.
a) At what time did he arrive in Leicester?
b) What was his average speed in mph?
Answer:
a. 12:10 pm
b. 40 mph
Step-by-step explanation:
Assuming you meant to type 1 ¹/₄ hours later.
a. First convert that to a improper fraction and then a decimal:
= 5/4
= 1.25 hours
1.25 hours in minutes is:
= 1.25 * 60
= 75 minutes
= 1 hour 15 minutes
The motorist left at 10:55.
= 1055 + 1 hour
= 11:55
Add 15 minutes:
= 12:10 pm
b. Speed = Distance / Time
= 50 / 1.25 hours
= 40 miles per hour

Arturo is driving at a speed of 50 miles per hour. At 2:00 he
sees the following sign.
Applebee
11 miles
Beauville
41 miles
Caanan
62 miles
Denton
98 miles
Arturo continues at the same speed. At 2:30 how far from
Caanan will he be?
A.
12 miles
B.
16 miles
C.
25 miles
D.
26 miles
E.
37 miles
Answer:
Your answer is 37
Step-by-step explanation:
Caanan is 62 miles away and since he drives at 50 miles per hour, and if it is 2:30 then 30 minutes is half a hour, which means you divide 50 in half by 2 and get 25. After you do that then you subtract 62 and 25 to get your answer 37. Have a good day!!! :)

Maria recently hired a plumber to do some necessary work. On the final bill, Maria was charged a total of $473. The amount listed for parts was $335 and the rest of the bill was for labor. If the hourly rate for labor was $46, how many hours of labor was needed to complete the job?
(A) First write an equation you can use to answer this question. Use x as your variable. The equation is __________________
(B) Solve your equation in part (A) to find the number of labor hours needed to do the job. Answer: The number of labor hours was ________________________
Answer:
A)473 = 335 - 46x
B) 3
Step-by-step explanation:
A)
473 = 335 - 46x
x = the hours of labor needed.
B)
Solve for x
473 = 335 - 46x
subtract 335 from both sides
138 = 46x
divide both sides by 46
3 = x
Answer:
A) [tex]46x+335=473[/tex] B)[tex]x=3[/tex]
Step-by-step explanation:
473 is the total amount, which means it is the end result
335 represents a constant since it is a base price
the hourly rate is a variable, due to the fact that it depends on how many hours he spent working.
variable + constant = total price
[tex]46x+335=473[/tex]
Now to solve this, first subtract [tex]335[/tex] from both sides
[tex]46x=138[/tex]
Next divide both sides by [tex]46[/tex] to isolate the variable
[tex]x= \frac{138}{46}[/tex]
This can be simplified to: [tex]x=3[/tex]
