Answer:
48 minutes
Step-by-step explanation:
Given: The distance between A and B is 8 miles. Speed of one jogger is 4 miles per hour, and speed of other jogger is 6 miles per hour.
To find: After how many minutes will the joggers meet, if they are running towards each other.
Solution:
Let both the joggers will meet after t hours, at point P between A and B.
We know that 
Let the jogger running at a speed of 4 miles per hour starts from point A.
So,



Let the jogger running at a speed of 6 miles per hour starts from point B.
So,



We have,





So, both the joggers will meet after 0.8 hours or
minutes.
Hence, the joggers will meet after 48 minutes.
Answer:
The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180
Step-by-step explanation:
The parameter given are;
To 12 × 15 by changing the numbers into friendlier numbers
The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;
12 × 15 = (10 + 2) × (10 + 5)
Which gives;
(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5
From which we have;
10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180
Therefore;
12 × 15 = 180.
