Answer:
4.5 < T < 5.5
Step-by-step explanation:
Nearest 5 minutes could be 4.5 to 5.49
The computation of the limits in between is shown below:
Now Multiply these numbers by 30
4.5 × 30 = 135
5.4 × 30 = 162
5.5 × 30 = 165
We can easily round 5.5 would to 6, since we cannot use 5.5.
Therefore
135 < T < 162
Therefore If the correct answer is 135 < T < 165
So it must be 4.5 < T < 5.5
