chen rode on his skateboard 3 3/4 miles in 3.4 of an hor. What was his average speed in miles per hour.
To find the average speed, we need to divide the total distance traveled by the total time taken.
Distance traveled = 3 3/4 miles = 3.75 miles
Time taken = 3.4 hours
Average speed = Distance traveled / Time taken
Average speed = 3.75 miles / 3.4 hours
Average speed ≈ 1.103 mph
Therefore, Chen's average speed on his skateboard was approximately 1.103 miles per hour.
it would be 5
Let's reevaluate the calculation:
Distance traveled = 3 3/4 miles = 3.75 miles
Time taken = 3.4 hours
Average speed = Distance traveled / Time taken
Average speed = 3.75 miles / 3.4 hours
Average speed ≈ 1.10294 mph
Therefore, Chen's average speed on his skateboard was approximately 1.103 miles per hour.
3 3/4 divided by 3/4 is 5
Let's calculate using the division method to verify:
3 3/4 miles is the same as 15/4 miles.
15/4 miles divided by 3.4 hours is:
(15/4) / 3.4 = (15/4) * (10/34) = (150/34) = 4.4118
Therefore, Chen's average speed on his skateboard was approximately 4.41 miles per hour.
where are you getting 15/4
I apologize for the confusion. Let's correct the calculation.
Chen rode 3 3/4 miles, which is the same as 15/4 miles.
Average speed = Distance traveled / Time taken
Average speed = (15/4) / 3.4
Average speed = (15/4) ÷ 3.4
Average speed = 15/4 * 10/34
Average speed = 1.103 mph
Therefore, Chen's average speed on his skateboard was around 1.103 miles per hour.
im still not understanding how ur getting that
I apologize for any confusion. Let's break it down step by step:
Given:
Distance traveled = 3 3/4 miles = 15/4 miles
Time taken = 3.4 hours
We need to calculate the average speed:
Average speed = Distance traveled / Time taken
Average speed = (15/4) miles / 3.4 hours
To divide by a fraction, we multiply by its reciprocal:
Average speed = (15/4) * (1/3.4)
Average speed = 15/4 * 1/3.4
Average speed = 15 / (4 * 3.4)
Average speed = 15 / 13.6
Average speed ≈ 1.103 mph
Therefore, Chen's average speed on his skateboard was approximately 1.103 miles per hour.
