Answer:
C) 60
Explanation:
For computing the difference between the time taken in minutes by Noel and Tyra first we have to compute individually which are as follows
For Noel, the time taken required
![= Time\ required * number\ of\ days](https://img.qammunity.org/2021/formulas/mathematics/college/x0w4mpk9bp4oxzi4rgfaboyphf5876tp1d.png)
![= 90\ minutes * 6\ days](https://img.qammunity.org/2021/formulas/mathematics/college/ec5vbobvui0xwheqpolvb11zzblb9pufbr.png)
= 540 minutes
For Tyra, the time taken required
![= Time\ required * number\ of\ days](https://img.qammunity.org/2021/formulas/mathematics/college/x0w4mpk9bp4oxzi4rgfaboyphf5876tp1d.png)
![= 60\ minutes * 8\ days](https://img.qammunity.org/2021/formulas/mathematics/college/v4thb6hm2wmhbbdtg0uqn77k13yv3etjl8.png)
= 480 minutes
So the difference is
= 540 minutes - 480 minutes
= 60 minutes
Hence, the third option is correct
