Explicação passo a passo:
28 carros >>>>>>>>>>>>>>>>>>1 minuto
56 >>>>>>>>>>>>>>>>>>>>>>>> x
28/56 = 1/x
28 * x = 56 * 1
28x = 56
x = 56/28 = 2 minutos resposta
b
28/168 = 1/x
28 * x - 168 * 1
28x = 168
x = 168/28 = 6 minutos resposta
c
28/224 = 1/x
28 * x = 224 * 1
28x - 224
x = 224/28 = 8 minutos >>>>>>resposta
