Q15. As shown in the image below, a man starts from point A, and tries to swim across a 40-ft wide river to point B on the other side, downstream at a distance d. The river flows with a constant velocity v, = 2.6 ft/s, with direction shown in the image. The man can swim at a speed vm/r = 6.0 ft/s in still water (which is the relative constant speed with respective to the flowing water). If the distance d = 43 ft, determine the magnitude of the man's absolute speed vm (with the effect of the flowing water) so he can arrive at point B. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. d d B. Vm/r_Vr 40 ft, 40 ft Vm Your Answer: Answer units

Please do this carefully.
It's saying this is not correct. Thank you for your help.
Answer this please. Thank you very much
Please answer number 6. with complete solutions and box the final answer.
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
Please walk me to find the answer and please include the magnitude of the force.
The attached answer was provided for the attached question. The equation uses the given temperature in celcius and the answer is also given in celcius. The temperature was used in the equation without converting from F and the answer was supposed to be in F. I am worried that even if I converted the answer to celcius that it would be correct because temperature was used in the equation using the incorrect unit.
