Calculate Intervals: Determine the total number of $7$ -minute intervals in $18$ minutes. $\newline$ To find out how many $7$ -minute intervals are in $18$ minutes, we divide $18$ by $7$ . $\newline$ $18 \div 7 = 2$ with a remainder of $4$ . $\newline$ This means Jom completes $2$ full $7$ -minute intervals and has an additional $4$ minutes.
Calculate Water Amount: Calculate the amount of water Jom drinks for the full $7$ -minute intervals. $\newline$ Since Jom drinks two bottles of $400$ ml water for every $7$ minutes, we multiply the number of full intervals by the amount of water he drinks per interval. $\newline$ $2$ intervals $\times 2$ bottles/interval $\times 400$ ml/bottle = $4$ bottles $\times 400$ ml/bottle. $\newline$ $4$ bottles $\times 400$ ml/bottle = $1600$ ml.
Check Additional Water: Determine if Jom drinks any additional water for the remaining $4$ minutes. $\newline$ Since Jom only drinks water in full $7$ -minute intervals, and he has only $4$ minutes remaining which is less than $7$ , he does not drink any additional water.
Sum Total Water: Sum up the total amount of water Jom drank. $\newline$ Jom drank a total of $1600\,\text{ml}$ from the full intervals. $\newline$ No additional water is added for the remaining $4$ minutes. $\newline$ Therefore, the total amount of water Jom drank is $1600\,\text{ml}$ .
