Question

After 1 hour, Shannon has biked 12 miles. If she yhen continued riding at an average rate of 8 miles per hour, how long did it take her to bike 44 miles?

Answer 1

It took Shannon 5 hours to bike 44 miles.

Explanation:

After 1 hour, Shannon was able to bike 12 miles. Since she biked a total of 44 miles, we can subtract the first 12 miles from her total: 44 - 12 = 32. Shannon road the remaining 32 miles at an average rate of 8 miles per hour. So, in order to find the time it took her to travel the remaining 32 miles, we need to divide the total number of miles left (32) by the average rate (8): 32/8 = 4. Since Shannon took 1 hour to bike 12 miles and an additional 4 hours to bike the remaining 32 miles, it took her 5 hours total for the 44 mile bike ride.

Answer 2

Answer: 5 hours.

Explanation:

1, You know that Shannon has biked 12 miles. To reach 44 miles she has to bike :

`44miles-12miles=32miles`

2. To calculate the time that took her to bike the other 32 miles you must apply the following formula

`t_(total)=t_1+d/V`

Where
`t_(total)` is the total time,
`t_1` is the time she took to bike 12 miles, d is distance and V is the speed

3. Then, you obtain the following result:

`t_(total)=1h+(32mi/8mi/h)`

`t_(total)=5h`
