ANSWER
6 mins.
EXPLANATION
The given graph completes one full cycle in 45 seconds because the graph repeats itself after every 45 seconds.
This means that the wheel makes one complete revolution in 45s.
This means that, the wheel will make 8 revolutions in 8×45s=360s.
1 min =60s
![360s = (360)/(60) = 6mins](https://img.qammunity.org/2020/formulas/mathematics/high-school/8xvzbwsg14lh7bjv5qbr408dzldxaqlvs5.png)
