Answer:
3/5
Step-by-step explanation:
drop the % cymbal from 60, divide the number 60 by 100, reduce the fraction 60/100 = 6/10, reducing this we get 6/10 = 3/5
Answer:
sorry, that is a very complex question
Step-by-step explanation:
it had to be more tjan 20 characters
<u><em>45×60=2700</em></u>
<u><em>And to check divide </em></u>
<u><em>2700÷60=40</em></u>
<u><em>2700÷40=60</em></u>
<u><em>Have a great time miss!</em></u>
Answer:
x = 49 mi/hr
y = 6 mi/hr
Step-by-step explanation:
A motorboat travels 258mi in 6 hours going upstream. It travels 330mi going downstream in same amount of time. What's the rate of the boat in still water and what is the rate of the current.
Let
x = the speed of the boat in still water.
y = the speed of the stream
The speed upstream is x - y
The speed downstream is x + y
Distance = rate × time
258 = (x - y)6 (1)
330 = (x + y)6 (2)
From (1)
x - y = 43 (3)
From (2)
x + y = 55 (4)
x - y = 43 (3)
x + y = 55 (4)
Add the equations to eliminate y
x + x = 43 + 55
2x = 98
x = 98/2
x = 49 mi/hr
Substitute x = 49 into (4)
x + y = 55 (4)
49 + y = 55
y = 55 - 49
y = 6 mi/hr
