Salma takes 15 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 2 m/s, calculate the distance between her house and the school.

Speed = 2 m/s
Time taken = 15 minutes = 15 × 60 seconds = 900 seconds
Now, distance = speed × time = 2 × 900 = 1800 m = 1.8 km

To calculate the distance Salma travels from her house to school, you can use the formula:
Distance = Speed x Time
Given:
Time taken = 15 minutes = 15 minutes × (60 seconds / 1 minute) = 900 seconds
Speed of the bicycle = 2 m/s
Now, use the formula to find the distance:
Distance = Speed x Time
Distance = 2 m/s x 900 s
Distance = 1800 meters
Therefore, the distance between Salma’s house and her school is 1800 meters (or 1.8 kilometers).
