Kendrick rides his bike x miles per hour to school and it takes him x+15 minutes to get there. If Kendrick lives 5.4 miles from school, how many minutes does it take for Kendrick to ride to school? Please help me!

Answers

did u write this correctly, if u did then x=5.4, then t= 5.4+15, t=20.4

Final answer:

In order to find Kendrick's biking time to school, set up and solve the equation based on the rate-time-distance relationship, using the given conditions of 5.4 miles distance, x miles per hour speed, and a time of x+15 minutes.

Explanation:

The subject of this question is rate, time, and distance. To find out how long it takes for Kendrick to bike to his school, we should start with the rate-time-distance relationship formula. If we let 'x' be the speed at which Kendrick rides his bike, then the time taken is simply 5.4 divided by x (since distance = rate x time, and we rearrange to get time = distance/rate).

However, the question states that the time is 'x+15' minutes. Therefore, we can set up the equation '5.4/x = x + 15.' Solving this equation will give us 'x' which is both the speed in miles per hour and the time in minutes that it takes Kendrick to bike to school.
