the rear – most end of a 66 foot truck exits a 330 foot tunnel exactly 6 seconds after the front – most end of the truck entered the tunnel . if the truck traveled the entire tunnel at a uniform speed , what is the speed of the truck in miles per hour ( 1 mile = 5,280 feet ) ?
total length will be 330 + 66 = 396 time = 6 secs speed = 396 / 6 = 66 feet / sec conversion to miles per hour = 66 * 3600 / 5280 = 45 . answer c
divide(multiply(divide(add(330, 66), 6), const_3600), add(multiply(add(const_4, const_1), const_1000), subtract(multiply(const_3, const_100), multiply(const_2, const_10))))
