Solve the following word problem. A man travels from Town X to Town Y at an average rate of 50 mph and returns at an average rat

777dan777 [17]

Distance = rate*time

Let distance from X to Y be 'd'

From the equation we can solve for 'time'

time = distance/rate

The total time it takes to go 50 mph ,then 40 mph is:

$\frac{d}{50} + \frac{d}{40}$

The total time it takes to go 45 mph round trip is:

$\frac{2d}{45}$

We know that the round-trip at 45 mph takes half-hour shorter, so by adding '1/2' to its time it will be equal to the time to go 50 then 40.

$\frac{2d}{45} + \frac{1}{2} = \frac{d}{50} + \frac{d}{40} \\ \\ \frac{4d+45}{90} = \frac{9d}{200} \\ \\ 800d+9000 = 810d \\ \\ 10d = 9000 \\ \\ d = 900$

Answer: The distance from X to Y is 900 miles.

Tap on image to see it all.....I really need this answer please

Olin [163]

Answer:

180-44=136 is d

then 180-136=44 44/2=22

c is 22. just remember total angle above straight line is 180, and the total angle of a triangle is also 180. And if two sides have the same length, their angles are also the same like c and a, and e and 44 degrees
