The required rate of change is 53 miles/hr
<h3>What is speed of a particle ?</h3>
The rate of change of position of a particle with respect to time is called speed of that particle.
Speed (Rate of change) = Distance/Time
<h3>What is the required rate of change ?</h3>
For 1st row,
Time = 4 hours
Distance = 212 miles
∴ Rate of change = Distance/Time
= 212/4 miles/hr
= 53 miles/hr
Similarly for 2nd row,
Rate of change = 318/6 miles/hr
= 53 miles/hr
Also for 3rd row,
Rate of change = 424/8 miles/hr
= 53 miles/hr
And for 4th row,
Rate of change = 530/10 miles/hr
= 53 miles/hr
So, here the constant rate of change is 53 miles/hr
From this result, we can say that if time & distance increases, then rate of change remains same for the object, i.e. the speed of the object is constant.
