Question

Sasha runs at a constant speed of 3.6 meters per second for

1/2 hour.​ Then, walks at a rate of 1.6 meters per second for
1/2 hour. How far did run and walk in ​60 minutes?

Answer 1

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

1.6 × 1/2 = 0.8 meters

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

1.9 + 0.8 = 2.7 meters
