 Question 635744: 1050^2Two children in nearby houses attempt to use walkie-talkies to communicate. The walkie-talkies reach one quarter of a mile (1320 feet). From one child's house to the other, the walk along the city sidewalks is as follows: Proceed 450 feet from the first house to the nearest corner, turn right 90 degrees and proceed another 1050 feet. Are the children's houses within the 1320-foot range of one another. A. No, but if the turn were to the left instead they would be within range B. Yes, as the distance formula indicates C. Yes, because city blocks are much smaller than one quarter of a mile D. No, because the diatance is greater than 1320 feet Click here to see answer by ewatrrr(10682)
