Two boys, shawn and curtis, went for a walk. shawn began walking 20 seconds earlier than curtis. shawn walked at a speed of 5 feet per second. curtis walked at a speed of 6 feet per second. for how many seconds had sean been walking at the moment on the two boys had walked exactly the same distance?

Roger and natalie travel in similar cars. roger's car drives the two miles to school in 7.5 minutes. natalie drives the same distance in the opposite direction but in only 6.5 minutes. what is true of their velocities?

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
