Mr. reciprocal started walking as his new year's resolution. he calculated that he can walk 1/2 mile in 1/4 of an hour. what is his walking rate in miles per hour

2 hours per hour cause 1/4=15 min 1/2 times 4 equals 2 so  2 miles per hour

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
