Question
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.

Solution
Time taken by Salma to reach her school from her home = 15 min
= 15 × 60
= 900s
Speed of her bicycle = 2 m/s
Speed = `"Distance covered"/"Time taken"`
Distance covered = Speed × Time taken
= 2 × 900
= 1800 m
= 1000 m = 1 km
∴ 1800 m = `1/1000 xx 1800 `
= 1.8 km
