The speed of car a after t minutes is 10*t m/s. how long will it take the car to travel 100/6 meters?

Speed is the distance traveled by a body per unit time. It is given by;
Speed= distance/time
In this case, the speed is 10 t meters/sec
Time is given by distance divided by speed
Hence, t = (100/6)10t
            10t² =100/6
                t² = 10/6
                t = √(10/6)
                t = 1.290 seconds

The answer would be 27 because assuming that each package has 1 bar of soap and 1 tube of toothpaste, after 27 packages they would run out of toothpaste
