Answer:45 MPH

Step-by-step explanation: Speed, distance and time can be calculated using a magic triangle. D (the distance) goes in the top of the triangle, S (speed) goes in the bottom left of the triangle and T (time) goes in the bottom right of the triangle.

Answer 2

Answer: The family travel at 45 miles per hour.

Step-by-step explanation:

Since we have given that

Number of miles away her grandmother lives = 45 miles

Time taken by her and her family = 1 hour

We need to find the rate that the family traveled.

Here, unit rate stands for "Speed at which she and her family travelling">

As we know the formula for "Speed":

$Speed=\dfrac{Distance}{Time}=\dfrac{45}{1}=45\ mph$

Hence, the family travel at 45 miles per hour.
