Answer:
- See below
Step-by-step explanation:
Speed = distance/time
1. Logan swam 750 meters in 1/3 of an hour
Logan's speed is:
- s = 750 : 1/3 = 750*3 = 2250 meters /hour
2. Mila swam 2/3 of Logan's distance:
- 2/3*750 = 500 meters
- Time is 1/4 of an hour
Mila's speed is:
- s = 500 : 1/4 = 500 * 4 = 2000 meters/hour
3. The difference is:
Logan is faster by: 2250 - 2000 = 250 meters/hour
