Question

Khloe, Trey, and Isiah are jamming out Katy Perry and start their road trip on the 18 mile marker and travel to the 147 mi. After driving 1.55 hours, Trey realized he forgot to get her Physics homework and tells Khloe to return to the CTC campus that is on the 24 mile marker to submit his work to Ms. Varona -). They get to the campus in 95 minutes. Their total distance is ____ m. Their total displacement is ____ m. mph ____ Their speed is ____. Their velocity is ____ mph.

Answer 1

The total distance traveled by Khloe, Trey, and Isiah is 166 miles, with a total displacement of 6 miles. Their speed is approximately 1.79 miles per minute, while their velocity is approximately 0.065 miles per minute.

Step-by-step explanation:

The total distance traveled by Khloe, Trey, and Isiah is 166 miles. This is calculated by adding the distance from the starting point (18 miles) to the campus (24 miles) to the distance from the campus back to the ending point (147 miles).

Their total displacement is 6 miles, which is the difference between the ending point (147 miles) and the starting point (141 miles). Since the displacement is in the opposite direction of their actual travel, it is negative.

The given time of 1.55 hours is equivalent to 93 minutes. To calculate the speed, we divide the total distance (166 miles) by the total time (93 minutes), which gives us a speed of approximately 1.79 miles per minute.

The velocity, on the other hand, takes into account the direction of motion. The displacement (6 miles) divided by the given time (93 minutes) gives us a velocity of approximately 0.065 miles per minute.
