Correct Answer - Option 3 : 52 Kms/hr

**Given:**

A car covers the first 35 Km of its journey in 45 minutes and covers the remaining 69 Km in 75 minutes

**Formula used:**

Average speed = Total distance/ Total time

Calculation

Total distance covered = 35 km + 69 km = 104 km

Total time = 45 minute + 75 minute = 120 min = 2 hours

Average speed = Total distance/ Total time

∴ Average speed = 104/2 = 52 km/hr
