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:

$\frac{4}{3}$ $\sqrt{3}$

Step-by-step explanation:

the ratio of sides of a 30-60-90° triangle, respectively, are 1 : $\sqrt{3}$ : 2

we can solve for 'x' using this proportion:

x/4 = 1/ $\sqrt{3}$

now cross-multiply:

$\sqrt{3}$ x = 4

x = 4/ $\sqrt{3}$

we don't want to leave a radical in the denominator so we can multiply numerator and denominator by $\sqrt{3}$ to get:

4 $\sqrt{3}$ / 3 or $\frac{4}{3}$ $\sqrt{3}$
