Answer:mark

Explanation:

mark swims at 4 kilometers in 1/10 hour.

Speed = Distance/Time

= 4/(1/10)

= 40km/hour

john swims at 5km/hour. It's faster by 35km.

= 40km - 5km

= 35km

To determine which option is faster, you can calculate the speed for each scenario using the formula:

Speed (in kilometers per hour) = Distance (in kilometers) / Time (in hours)

1. For the first scenario: 4 kilometers in 1/10 hour

Speed = 4 km / (1/10) hour = 4 km / 0.1 hour = 40 kilometers per hour

2. For the second scenario: 5 kilometers in 1/4 hour

Speed = 5 km / (1/4) hour = 5 km / 0.25 hour = 20 kilometers per hour

Now, comparing the speeds:
- In the first scenario, the speed is 40 kilometers per hour.
- In the second scenario, the speed is 20 kilometers per hour.

So, the first scenario (4 kilometers in 1/10 hour) is faster because the speed is 40 kilometers per hour, while the second scenario (5 kilometers in 1/4 hour) has a speed of 20 kilometers per hour.
