Aboat travels upstream on the allegheny river for 2hours. the return trip only takes 1.7 hours because the boat travels 2.5 miles per hour faster downstream due to the current. how far does the boat travel in one day?

= 28.332 miles

Step-by-step explanation:

Distance= speed × time

The distance in this problem would be the same up or downstream

Let the speed be x upstream and ( x +2.5) downstream

2x = 1.7 (x+2.5)

0.3x = 1.7 (2.5)

X = 14.166

Now multiply by 2 to fund the distance one way

Distance = 14.166×to

= 28.332 miles

sry but any answer choices

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
