Answer : 3. "60 kmph"
Explanation :
Answer: C) 60 kmph Explanation: Average speed = Total distance / Total time. Total distance traveled by Joel = Distance covered in the first 3 hours + Distance covered in the next 5 hours. Distance covered in the first 3 hours = 3 x 60 = 180 milesDistance covered in the next 5 hours = 5 x 24 = 120 miles Therefore, total distance traveled = 180 + 120 = 300 miles. Total time taken = 3 + 5 = 8 hours. Average speed = 300/8 = 37.5 mph. we know that 1 mile = 1.6 kms => 37.5 miles = 37.5 x 1.6 = 60 kms Average speed in Kmph = 60 kmph.
