Answer:
220 miles
Step-by-step explanation:
Given the following data;
Distance = 385 miles
Take-off time = 8 AM
Speed = 55 mph
To find how far would he be by noon;
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]
Making time the subject of formula, we have;
[tex]Time = \frac{distance}{speed}[/tex]
Substituting into the equation, we have;
[tex]Time = \frac{385}{55}[/tex]
Time = 7 hours
This ultimately implies that, he covers 55 miles per hour.
Next, we would determine how far he would be by noon.
Noon = 12 PM
By noon, time = 12 - 8 = 4 hours
Distance = speed * time
Distance = 55 * 4
Distance = 220 miles
Therefore, Larry's father would have covered a distance of 220 miles by noon.
