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>
Answer:
5/6 of the time or 50 minutes
Step-by-step explanation:
The given equation solved for A is A = (T + 5)/ B
<h3>Solving linear equation</h3>
From the question, we are to solve the given equation for A
To solve the equation for A, we will simply make A the subject of the equation
The given equation is
T = AB - 5
Solving for A
T = AB - 5
Add 5 to both sides of the equation
T + 5 = AB - 5 + 5
T + 5 = AB
Divide both sides of the equation by B
That is,
(T + 5)/B = AB/B
(T + 5)/B = A
∴ A = (T + 5)/ B
Hence, the given equation solved for A is A = (T + 5)/ B

Step-by-step explanation:
Convert the given value in cm into feet and inches.
<u>Use the unit rates:</u>
- 1 foot = 30.48 cm
- 1 inch = 2.54 cm
<u>Convert:</u>
- 170 cm = 170/30.48 feet = 5.58 feet (rounded)
- 170 cm = 170/2.54 inches = 66.93 inches
or
- 170 cm = 5 feet and 17.6 cm = 5 feet and 7 inches (rounded)
Answer:
laps can Fred run in one hour.
Step-by-step explanation:
Given Statement: Fred is running on the school track. He can run 
laps in 
of an hour.
Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates
From the given condition we have;
In he can run 
laps
Unit rate per hour = 
=
laps
Therefore, Fred can run in one hour is, laps.
