The maximum height of a vehicle that can safely pass under a bridge is 12 feet 5 inches. a truck measures 162 inches in height. which best explains whether or not the truck can pass safely under the bridge?

Eight of the truck =m 162 inches
height of the bridge under which vehicles pass = 12 feet 5 inches
                                                                            = (12 * 12) + 5 inches
                                                                            = 144 + 5 inches
                                                                            = 149 inches
we arrived at the above deduction from the fact that 1 feet is equal to 12 inches.
now 
difference in height of the truck and the bridge is = 162 - 149 inches
                                                                              = 13 inches
