30 <p>What is the rate of change in temperature if it increases from 20°C to 35°C over 3 hours?</p>

29 <p>What is the rate of change in temperature if it increases from 20°C to 35°C over 3 hours?</p>

31 <p>Okay, lets begin</p>

30 <p>Okay, lets begin</p>

32 <p>Use the formula: Rate of Change = (Final Value - Initial Value) / Time Period Rate of Change = (35 - 20) / 3 ≈ 5°C per hour</p>

31 <p>Use the formula: Rate of Change = (Final Value - Initial Value) / Time Period Rate of Change = (35 - 20) / 3 ≈ 5°C per hour</p>

33 <h3>Explanation</h3>

32 <h3>Explanation</h3>

34 <p>By subtracting the initial temperature from the final temperature and dividing by the time period, we find the rate of change in temperature is 5°C per hour.</p>

36 <p>A car speeds up from 40 km/h to 100 km/h in 15 seconds. What is its rate of change in speed?</p>

38 <p>Okay, lets begin</p>

37 <p>Okay, lets begin</p>

39 <p>Use the formula: Rate of Change = (Final Value - Initial Value) / Time Period Rate of Change = (100 - 40) / 15 ≈ 4 km/h per second</p>

38 <p>Use the formula: Rate of Change = (Final Value - Initial Value) / Time Period Rate of Change = (100 - 40) / 15 ≈ 4 km/h per second</p>

40 <h3>Explanation</h3>

39 <h3>Explanation</h3>

41 <p>Subtracting the initial speed from the final speed and dividing by the time period gives us a rate of change of 4 km/h per second.</p>
