Answer- 3391.2mile
Explanation:
Greetings !
Firstly, recall distance-speed equation
![speed = (distance)/(time)](https://img.qammunity.org/2023/formulas/mathematics/high-school/etxa7fbao5e59dm553miru5mpk8u44es98.png)
Given values:-
- speed(v)=15.7mile/hr
- time(t)=9days
required values:-
solution /work-out
But, first change the time from day to hour
Thus, 9days=216hours
![distance = speed * time](https://img.qammunity.org/2023/formulas/mathematics/high-school/zzfhou53hfto7k4pu6h1t6x0bm9zur5dys.png)
plug in the given values and solve for the distance.
![distance = 15.7mi</strong><strong>\</strong><strong>hr * 216hr \\ distance = 3391.2mile](https://img.qammunity.org/2023/formulas/mathematics/high-school/rng32t8snrfue6seryvlkxtsvv84q0c4wj.png)
Hope it helps!
