Answer 1

Lamar's cart moved 48 meters while his daughter was walking beside it, calculated by multiplying the time she walked (24 seconds) by the speed of the cart (2 meters per second).

Step-by-step explanation:

Lamar pushed his shopping cart toward his car at 2 meters per second, and it took him 72 seconds to reach his car. His daughter walked with him for one-third of that time.

To find out how far the cart moved while his daughter was walking beside it, we calculate one-third of the time and then use the speed to determine the distance traveled.

One-third of 72 seconds is 24 seconds (72 / 3).

Multiplying the time by the speed of the cart (24 seconds × 2 meters/second), we find that the cart moved 48 meters while Lamar's daughter was walking beside it.
