Answer:
Average speed, S = 45 mph
Step-by-step explanation:
Given the following data;
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;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting into the formula, we have;
[tex]Speed = \frac{270}{6}[/tex]
Average speed, S = 45 mph
Therefore, the average speed of the bus is 45 miles per hour.
