Answer:
Train
Explanation:
To get the success rate (on time) of bus, we need to divide 56 by 64. So:
![(56)/(64)=(7)/(8)\\=0.875](https://img.qammunity.org/2020/formulas/mathematics/middle-school/cx9xdhj9pki2lo13m5mpxj3s7a2wfo2v9n.png)
This multiplied by 100 gives us the %. Thus, 0.875 * 100 = 87.5%
Clearly, 90% is greater than 87.5%. Hence, based solely on times, the train provides best service.
