Answer
a. The drive was 2 hours.
b. His average speed was 60 miles per hour.
Solution
To solve the problem, we start with the rate equation: r = d/t.
a. Ibram leaves at 3:45 p.m. and arrives at 5:45 p.m., which means the drive lasted 2 hours.
b. His average speed is calculated as follows:
Average speed = Total distance / Total time = 120 miles / 2 hours = 60 miles per hour.
Thus,
a. The drive was 2 hours.
b. His average speed was 60 miles per hour.

The drive was 2 hours long. If Ibram left at 3:45 p.m. and arrived at 5:45 p.m., the time taken for his journey can be calculated by finding the difference between the two times, which gives us 2 hours. His average speed was 60 miles per hour. Using the rate equation \( r = \frac{d}{t} \), we can substitute \( d = 120 \) miles and \( t = 2 \) hours. Thus, \( r = \frac{120}{2} = 60 \) miles per hour. Ibram was cruising along nicely!
