Answer» Answer: Sally Malin was FASTEST Step-by-step explanation: In ORDER to find who was the fastest either SCOTT or Sally, we must find their speed in their journey. We know that, Speed = Distance/Time • For Scott : Distance = 100m Time = 20 sec Speed = Distance/Time = 100/20 = 5 m/sec Hence, speed of Scott = 5 m/sec • For Sally : Distance = 200 m Time = 39 sec Speed = Distance/Time = 200/39 = 5.1282 m/seconds Hence, speed of Scott = 5.1282 m/sec From above OUTCOMES, we can see that, 5.1282 m/sec > 5 m/sec Hence, speed of Sally > Speed of Scott Thus, Sally Malin was fastest. |
