Detailed Solution
Download Solution PDFGiven:
Rachin travels:
1st part: Speed = 60 km/h, Time = 2 hr
2nd part: Distance = 80 km, Speed = 40 km/h
Formula used:
Average speed = Total distance / Total time
Calculation:
Distance of 1st part = 60 × 2 = 120 km
Time for 2nd part = 80 ÷ 40 = 2 hr
Total distance = 120 + 80 = 200 km
Total time = 2 + 2 = 4 hr
⇒ Average speed = 200 ÷ 4 = 50 km/h
∴ The correct answer is 50 km/h.
