Question:

The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30 pm. Faris assumes that the coach will travel at an average speed of 50 mph; using his assumption workout Faris’s arrival time in London

Answer:

$Arrival = 7:24pm$

Step-by-step explanation:

Given

$Distance = 195\ miles$

$Speed = 50mi/hr$

$Take\ off = 3:30\ pm$

Required

Determine the time of arrival

First, we need to calculate the time to complete the journey.

$Speed = \frac{Distance}{Time}$

Make Time the subject

$Time= \frac{Distance}{Speed }$

Substitute values for Distance and Speed

$Time= \frac{195mi}{50mi/hr}$

$Time= 3.9hr$

The arrival time is:

$Arrival = Take\ off + Time\ Taken$

$Arrival = 3:30pm + 3.9\ hours$

Split

$Arrival = 3:30pm + 3\ hours + 0.9\ hours$

$Arrival = 6:30pm + 0.9\ hours$

Convert 0.9 hours to minutes

$Arrival = 6:30pm + 0.9 * 60\ mins$

$Arrival = 6:30pm + 54\ mins$

$Arrival = 7:24pm$

Answer:

13.31803792

Step-by-step explanation:

<u>Law of Cosines</u>

a= 8

b= 18

c= ?

$c^2=a^2b^2-2ab*cos(c)$

$c^2=8^2-18^2-2*8*18*cos(43)$

c = 64 + 324 - 2 * 8 * 18 * cos(43)

cos(43) = 0.7313537016

<u>Order of Operations</u>

64 + 324 - 2 * 8 * 18 * 0.7313537016 = 177.3701339

<u>Square Root the answer</u>

$\sqrt{177.3701339}$ = 13.31803792
