Try, please, suggested decision.
6+4/5a=9/10a
make bottom numbers same
into 10
60/10+8/10a=9/10a

60/10=1/10a
multiply both sides by 10
60=a
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The distance is
.
- The time is
.
2. Therefore, you must divide the distance by the time to calculate the average speed:
![V=d/t\\ V=112miles/12hours\\ V=9.33 miles/hour](https://tex.z-dn.net/?f=%20V%3Dd%2Ft%5C%5C%20V%3D112miles%2F12hours%5C%5C%20V%3D9.33%20miles%2Fhour%20)
The answer is: ![9.33miles/hour](https://tex.z-dn.net/?f=%209.33miles%2Fhour%20)
