Question

A boy riding his bicycle has a speed of 12 m/s as he approaches a hill. After 15 seconds it reaches the top and has a speed of 8 m/s. how far did the child travel?

Answer 1

To determine the distance traveled by the boy on his bicycle, we can use the equation: distance = speed x time. Given that the boy's initial speed was 12 m/s and it took him 15 seconds to reach the top of the hill with a final speed of 8 m/s, the total distance traveled by the boy is 300 meters.

Step-by-step explanation:

To determine the distance traveled by the boy on his bicycle, we can use the equation:

distance = speed x time

Given that the boy's initial speed was 12 m/s and it took him 15 seconds to reach the top of the hill with a final speed of 8 m/s, we can calculate:

1. Distance traveled uphill: distance = speed x time = 12 m/s x 15 s = 180 meters
2. Distance traveled downhill (assuming he traveled the same distance down the hill): distance = speed x time = 8 m/s x 15 s = 120 meters
3. Total distance traveled: 180 meters + 120 meters = 300 meters
