Answer:
Area of room = 21 * 16
= 336 m²
Area of Carpet = (21 - 1)* (16-1)
= 20*15
= 300
Area of border = Area of room - Area of carpet
= 336 - 300
<h3>= 36 m².</h3>
Answer:
Average speed, S = 45 mph
Step-by-step explanation:
<u>Given the following data;</u>
Take-off time = 10 AM
Arrival time = 4 PM
Distance = 270 miles
To find the average speed of the bus;
First of all, we would determine the total time.
10 AM to 4 PM = 6 hours
Total time = 6 hours
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;

Substituting into the formula, we have;

<em>Average speed, S = 45 mph</em>
<em />
<em>Therefore, the average speed of the bus is 45 miles per hour.</em>
