Question

Jim went by bus to visit his uncle. He left at 10 A.M. and arrived at 4 P.M. The bus traveled 270 mi. What was its average speed?​

Answer 1

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;

$Speed = \frac{distance}{time}$

Substituting into the formula, we have;

$Speed = \frac{270}{6}$

Average speed, S = 45 mph

Therefore, the average speed of the bus is 45 miles per hour.
