aubrey can walk 4 1/2 miles in 1 1/2 hours. find her average aspeed in miles per hour.
Divide distance 4 1/2 by 1 1/2 you will get 3 (miles per hour). Please check exact math using the calculator but I believe it is right
Tori can walk 41/2 miles in 1/2 hours. Find her average speed in miles per hour.
To find Aubrey's average speed in miles per hour, we will divide the total distance she walked by the total time it took her.
Total distance walked: 4 1/2 miles
Total time taken: 1 1/2 hours
To add the distances, convert the mixed number to an improper fraction:
4 1/2 = (8/2) + 1/2 = 9/2
To add the times, convert the mixed number to an improper fraction:
1 1/2 = (3/2)
Now, divide the total distance by the total time:
Average speed = (Total distance) / (Total time) = (9/2) / (3/2)
To divide fractions, we multiply the first fraction by the reciprocal of the second:
Average speed = (9/2) * (2/3) = (9 * 2) / (2 * 3) = 18/6
Simplifying the fraction:
Average speed = 3 miles per hour
Therefore, Aubrey's average speed is 3 miles per hour.
To find Aubrey's average speed in miles per hour, we need to divide the total distance she walked by the total time it took her. In this case, Aubrey walks 4 1/2 miles in 1 1/2 hours.
To simplify the calculation, let's convert the fractions into decimals:
- 4 1/2 miles = 4.5 miles
- 1 1/2 hours = 1.5 hours
Now, we can divide the distance by the time:
Average speed = Total distance ÷ Total time
Average speed = 4.5 miles ÷ 1.5 hours
Dividing 4.5 by 1.5 gives us:
Average speed = 3 miles per hour
Therefore, Aubrey's average speed is 3 miles per hour.
