Answer:
387
Step-by-step explanation:
Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m

Answer:
14.5 × 3.18 - 14.5 x 1.88
You paid $18.85 more in june than in February
Step-by-step explanation:
In order to find the answer to this question you will need to find how much you paid in June and how much you paid in February.
ex.14.5 x 3.18 - 14.5 x 1.88
To solve this you need to find the product of 14.5 x 3.18 and 14.5 x 1.88 and then subtract them from eachother.
ex.14.5 x 3.18 =46.11
14.5 x 1.88=27.26
46.11-27.26=18.85
