Answer:
10.35 miles per hour
Sam's rate as stated is 63,756 feet per 70 minutes
Divide by 5,280 feet
Divide by 60 minutes
Step-by-step explanation:
1. Find how many feet Sam ran in one minute
63,756 ÷ 70 = 910.8 ft.
2. Find how many feet he ran in one hour
910.8 · 60 = 54,648 ft.
3. Convert the feet to miles
54,648 ÷ 5280 = 10.35
Step 2: There are 5280 feet in one mile. Therefore, you would divide by 5280 feet to convert feet per minute into miles per minute.
Step 3: There are 60 minutes in one hour. Therefore, you would divide by 60 minutes to convert miles per minute to miles per hour.
Option D:
The dimensions of the matrices don't align properly to find their sum.
Solution:
Given data:
Dimension of matrix = Number of rows × Number of columns
Dimension of matrix is 2 × 1
Dimension of matrix is 2 × 2
Here, we have to add the two matrices.
<em>The dimension of the matrices must be same to add or subtract matrices.</em>
Here the dimensions are 2 × 1 and 2 × 2.
The dimensions are not same.
Hence we can't find their sum.
Option D is the correct answer.
The dimensions of the matrices don't align properly to find their sum.
