In April, a Jamaican tourist changed JM $50,000 into American currency. Calculate the amount of US dollars he received. USD $1.0
1 answer:
Answer:
USD $342.47
Step-by-step explanation:
For these kinds of questions, I like to use what I call the 'I want... If' method. I'll walk you through my thought process. Essentially, when I write my formula, I think, 'I want to find out how many US dollars I can receive from JMD $50,000 if JMD $146 is USD $1.
Essentially, the 'I want to find out... $50,000' part goes in the nominator of a fraction. 'If JMD $146' goes in the denominator of the same fraction. Then, add a multiply operator and finally 'is USD $1' goes after the operator.
In working, it looks like this:
JMD $ x USD $1 = USD $342.4657534247 = USD $342.47 (To 3 s.f.)

Answer:
<em>The speed of a boat in still water is 6 miles per hour. </em>
Step-by-step explanation:
t = (upstream)
t = (downstream)
=
40 ( s - 2 ) = 20 ( s + 2 )
40s - 80 = 20s + 40
20s = 120
s = 6 mi / h
<em>The speed of a boat in still water is 6 miles per hour.</em>
