b) 4.2 hours
c) 8.4 hours
d) 12.6 hours

Answer 1

To complete the London Marathon, it will take the athlete approximately 2.33 hours, which is not one of the options provided.

Step-by-step explanation:

To calculate the time it will take to complete the London Marathon, we need to know the distance of the marathon and the speed at which the athlete is jogging. The London Marathon is approximately 42 kilometers long. Given that the athlete is jogging at 5 m/s, we can use the formula time = distance / speed. By substituting the values, we get time = 42,000 m / 5 m/s = 8,400 s. In order to convert the time to hours, we divide by 3600 (60 seconds x 60 minutes) and get approximately 2.33 hours.

Therefore, the correct answer is not given in the options provided. It will take the athlete approximately 2.33 hours to complete the London Marathon.
