Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour. Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. How far did Sasha run and walk in 60 minutes?

Step-by-step explanation:

Distance covered = speed * time.

Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.

This means distance covered while running would be

3.8 * 1/2 = 1.9 meters

Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be

1.5 * 1/2 = 0.75 meters

Total distance that Sasha covered while running and walking in 60 minutes would be

1.9 + 0.75 = 2.65 meters
