how can i solve this question

1. my brother left Accra to central region 7:12am and reached 10:45 cover to 180 miles how many per hour?

10:45 - 7:12 = 3 hours, 33 minutes = 3.55 hours

180 / 3:55 = 50.7 miles per hour

To solve this question and find the average speed in miles per hour, you need to use the formula:

Average Speed = Total Distance / Total Time

Let's break down the given information:

- Total Distance: 180 miles
- Total Time: The time it took to travel from Accra to the central region, which is 7:12 am to 10:45 am.

To find the total time taken, you need to subtract the start time (7:12 am) from the end time (10:45 am):

End Time - Start Time = Total Time

Converting the times to minutes:
- Start Time: 7:12 am = 7 × 60 + 12 = 432 minutes
- End Time: 10:45 am = 10 × 60 + 45 = 645 minutes

Subtracting the start time from the end time:
Total Time = 645 minutes - 432 minutes = 213 minutes

Now that you have the total distance and total time, you can use the formula to find the average speed:

Average Speed = Total Distance / Total Time
= 180 miles / 213 minutes

To convert the answer to miles per hour, you need to convert minutes to hours. Since there are 60 minutes in an hour:

Average Speed = (180 miles / 213 minutes) × (60 minutes / 1 hour)
= (180 miles × 60 minutes) / (213 minutes × 1 hour)
= 10800 miles / 213 hours

After evaluating the above expression, you get the average speed:

Average Speed ≈ 50.7 miles per hour (rounded to one decimal place)

So, the average speed is approximately 50.7 miles per hour.
