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?
Answers
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

Simplify the expression to lowest terms. 4x^2 - 9/2x^2+11x+12
Answers
Answer:
(2x - 3)/(x +4)
Step-by-step explanation:
Given the expression 4x^2 - 9/2x^2+11x+12
Simplify the numerator
4x^2 - 9 = (2x)^2 - 3^2
Recall that a^2 - b^2 = (a-b)(a+b)
Hence 4x^2 - 9 = (2x - 3)(2x + 3)
The denominator
2x^2+11x+12
Factorize
2x^2+11x+12 = 2x^2+8x + 3x+12
=2x(x + 4) + 3(x + 4)
= (2x + 3)(x + 4)
Hence
4x^2 - 9/2x^2+11x+12 = (2x - 3)(2x + 3)/(2x + 3)(x + 4)
= (2x - 3)/(x +4)

Which equation represents a line which is perpendicular to the line x – 2y = -14?
Answers
Answer:
any equation that have the slope of -2
A line which is perpendicular to the line x – 2y = -14 will have a slope of -2
What is a slope?The slope of a line is a measure of its steepness.
Given an equation of a line x – 2y = -14
We know that, the slope of a line perpendicular to another line will have a slope of its negative reciprocal.
Therefore, slope of the line perpendicular to the line x – 2y = -14 will be -2
Hence, equation of the line perpendicular to the line x – 2y = -14 will have a slope of -2
