ACTIVITY 3 1. Jonathan bought three lengths of wood: 3.5 m : 2 m ; and 2.75 m . How much wood did he buy in total? 2. The following volume of goods was transported by road and rall: In 2002: 670192 tons In 2003: 689.670 tons 2.1. How many tons were transported during 2002 and 2003 altogether? 2.2. Now write the total number of tons in words. 3. Ramon gives his friend his address: 1834 Norman Heights, Hillbrow. Johannesburg. 3.1. What floor does Ramon live in? 3.2. What is Ramon's flat number? 4. Miners travel \( 1500 m \) below ground every day. How would you indicate the downard distance they travel? 5. On Sunday aftemoon the temperature in Portland was \( 2^{\circ} \mathrm{C} \). By midnight the temperature had dropped by \( 8^{\circ} \mathrm{C} \). What was the temperature at midnight?

Let's solve each part of the activity step by step. ### 1. Total Length of Wood Bought by Jonathan Jonathan bought three lengths of wood: - \( 3.5 \, \text{m} \) - \( 2 \, \text{m} \) - \( 2.75 \, \text{m} \) To find the total length of wood, we will add these lengths together: \[ \text{Total Length} = 3.5 + 2 + 2.75 \] Calculating this: \[ \text{Total Length} = 3.5 + 2 + 2.75 = 8.25 \, \text{m} \] ### 2. Volume of Goods Transported In 2002, the volume transported was \( 670192 \, \text{tons} \) and in 2003 it was \( 689670 \, \text{tons} \). #### 2.1 Total Tons Transported in 2002 and 2003 To find the total tons transported, we will add the two years together: \[ \text{Total Tons} = 670192 + 689670 \] Calculating this: \[ \text{Total Tons} = 670192 + 689670 = 1351862 \, \text{tons} \] #### 2.2 Writing the Total Number of Tons in Words The total number of tons transported is \( 1351862 \). In words, this is: **One million three hundred fifty-one thousand eight hundred sixty-two tons.** ### 3. Ramon's Address Ramon's address is given as: **1834 Norman Heights, Hillbrow, Johannesburg.** #### 3.1 What Floor Does Ramon Live On? The number **1834** typically indicates the flat number and the building number. Therefore, we cannot determine the floor from this information alone. #### 3.2 What is Ramon's Flat Number? Ramon's flat number is **1834**. ### 4. Indicating the Downward Distance Miners Travel Miners travel \( 1500 \, \text{m} \) below ground. To indicate the downward distance, we can use a negative sign: \[ \text{Downward Distance} = -1500 \, \text{m} \] ### 5. Temperature Change in Portland On Sunday afternoon, the temperature was \( 2^{\circ} \mathrm{C} \). By midnight, it dropped by \( 8^{\circ} \mathrm{C} \). To find the temperature at midnight, we will subtract the drop from the initial temperature: \[ \text{Midnight Temperature} = 2 - 8 \] Calculating this: \[ \text{Midnight Temperature} = 2 - 8 = -6^{\circ} \mathrm{C} \] ### Summary of Answers 1. Total length of wood: **8.25 m** 2. Total tons transported: **1351862 tons** - In words: **One million three hundred fifty-one thousand eight hundred sixty-two tons.** 3. Ramon's address: - Floor: **Cannot be determined** - Flat number: **1834** 4. Downward distance: **-1500 m** 5. Midnight temperature: **-6°C**
