Alicia went on a steamboat ride up the Mississippi River. The boat travels 20 miles per hour in still water. How long will it take her to travel 144 miles upstream if the current of the river is 8 miles per hour?
the upstream speed will be 20-8 = 12 mph
144/12 = 12, so 12 hours
10 hours. Don't forget that the water is not still.
That is not right the answere is 5
To find out how long it will take Alicia to travel 144 miles upstream, we can use the formula distance = rate × time. In this case, Alicia's rate is the speed of the boat in still water minus the speed of the current of the river.
First, let's calculate Alicia's rate upstream. Since the boat is traveling upstream, its speed will be reduced by the speed of the current. Hence, the rate upstream will be 20 miles per hour (speed of the boat) minus 8 miles per hour (speed of the current) which equals 12 miles per hour.
Now, using the formula distance = rate × time, we can rearrange it to solve for time: time = distance / rate.
Substituting the given values, we have distance = 144 miles and rate = 12 miles per hour.
Plugging the values into the formula: time = 144 miles / 12 miles per hour.
Now, divide 144 by 12 to get the answer:
time = 12 hours.
So, it will take Alicia 12 hours to travel 144 miles upstream.
