Detailed Solution
Download Solution PDFGiven data:
Sajid drives for 6 hours at 60 km/hr
Sajid drives for 4 hours at 50 km/hr
Concept: Average speed = Total distance / Total time
Solution:
⇒ Total distance covered = (6 hours × 60 km/hr) + (4 hours × 50 km/hr) = 360 km + 200 km = 560 km
⇒ Total time = 6 hours + 4 hours = 10 hours
⇒ Average speed = 560 km / 10 hours = 56 km/hr
Therefore, Sajid's average speed for the whole journey is 56 km/hr.
