Answer 1

Answer:

I believe its 5 miles per hour

Answer 2

Answer:

1. 5 miles/hour

2. 12 apples

Step-by-step explanation:

1. Mary drove 55 miles in 11 hours.

To find the unit rate of her speed we will use the formula

Speed = $\frac{Distance}{time}$

           = $\frac{55}{11}$

           = 5 miles/hour

The unit rate of Mary's speed would be 5 miles per hour.

2. The ratio of apples to oranges = 3 : 15 = $\frac{3}{15}$

                                                                   = $\frac{1}{5}$

Let the total number of apples be x.

Therefore, $\frac{x}{60}$ = $\frac{1}{5}$

By multiplying with 60 on both the sides.

x = $\frac{60}{5}$

x = 12

The number of apples are 12.
