5 0

Answer:

His error occurred in the last step

Explanation:

He was supposed to calculate -

\frac{5}{6}  - \frac{1}{9} \\or\\\frac{15}{18}  - \frac{2}{18} \\

which would equal -

\frac{13}{18} \\not\\\frac{17}{18}

Because he added instead of subtracted.

Hope this helps!

Read the word problem below.
salantis [7]

Answer:

1 3/5 miles/hr

Step-by-step explanation:

Let C be the speed of the current

Let D be the distance between Chan's house and the park

We know that Distance, D, is = Speed x Time

-----

Chan's speed going upstream is (8 - C)mph.

That gives us:

D = (8-C)(3 hr)

Chan's speed going downstream is (8+C)mph

So we have:

D = (8+C)(2 hr)

We know that the d is the same for these two equations, so:

(8-C)(3 hr)  = (8+C)(2 hr)

24 - 3C = 16 + 2C

5C = 8

C = (8/5) or 1 3/5 mph
