Acar left point a at 7: 30 am and arrived at point b, 162 miles away at 10: 30 am. what was its average speed in miles per hour?

The formula for average speed is,

S= Total Distance Covered / Total Time Taken

In the given problem, 

The total distance covered is 162 miles.
Since only the times are given, we have to determine how many hours did the car traveled from 7:30am to 10:30am.

To get the number of hours: First, subtract the hours, then the minutes. Hours: 10-7=3 
Minutes: 30-30=0

Therefore,

S = 162miles/3hrs
S = 54miles/hr

The average speed of the car is 54miles/hr.

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )

What does the start look like
