Example 3 The distance between Ajay's school and his home is 827 m. He walks to school in the morning and then walks back home in the evening, 6 days a week. How much does he walk in a week? Answer in kilometres.Let’s convert all distances into kilometers We know that 1000 m = 1 km 1 m = 𝟏/𝟏𝟎𝟎𝟎 km Now, Distance between Ajay’s school and home = 827 m = 827 Γ— 𝟏/𝟏𝟎𝟎𝟎 km = 0827/1000 km = 0.827 km Now, given that He walks to school in the morning and then walks back home in the evening, 6 days a week. How much does he walk in a week? Thus, Distance walked in 1 day = 2 Γ— 0.827 km And, Distance walked in 1 week = Distance walked in 6 day = 6 Γ— Distance walked in 1 day = 6 Γ— 2 Γ— 0.827 km = 6 Γ— 2 Γ— 827/1000 km = 6 Γ— 2 Γ— 827 Γ— 𝟏/𝟏𝟎𝟎𝟎 km = 9924 Γ— 1/1000 km = 9.924 km Thus, Ajay walks 9.924 km a week.
