2. Two numbers have a suill the numbers. 3. A truck was travelling at 23 m/s. It decelerated for 15 s. The distance travelled by the truck, d metres, during this time is given by the formula d = 23t - 0.612 , where t is the time in seconds. How long did it take the truck to travel 60 m to the nearest tenth of a second? Iving, determine whether each equation has one, two or no real roots
