with process​

Answer 1

Answer:

3.54 m/s

Step-by-step explanation:

Total distance needs to cover = 65 km

Time to cover the total distance = 5 hours

Speed in the first half,

Distance covered = 42 km = 42,000 m

Time taken to cover the distance = 3 hours = 3 × 60 × 60 = 10,800 seconds

Speed in the first half = 42000/10800 = 3.89 m/s

Distance remaining = 65 - 42 = 23 km = 23,000 m

Time remaining = 5 – 3 = 2 hours = 2 × 60 × 60 = 7,200 seconds

Required speed = 23000/7200 = 3.19 m/s

Average of speeds = (3.89 + 3.19)/2 = 7.08/2 ∴ Average of speeds = 3.54 m/s
