Answer:
15 m/h
Explanation:
The rate of a balloon is calculated by dividing the distance traveled by the time taken. In this case, the rate is given by:
![\[ \text{Rate} = \frac{\text{Distance}}{\text{Time}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/oqwgmdqlqx7oj91a7ol53p971cxogm5b0p.png)
Substitute the given values:
![\[ \text{Rate} = \frac{60\ \text{miles}}{4\ \text{hours}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/4rxn2jtzntd0skb70dq2xm6rgxy0t40p0s.png)
Simplify the expression:
![\[ \text{Rate} = 15\ \text{miles per hour} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/pszzgozl6074cs4qxm23lhxi4y006px55o.png)
Therefore, the rate of the balloon is 15 miles per hour.
