Question

Four students walk home from school. Tom walks for 25 min at a speed of 5.0 km/h. Juan walks for 22 min at a speed of 4.2 km/h. Alicia walks for 32 min at a speed of 4.5 km/h. Petra walks for 40 min at a speed of 3.5 km/h. Which student walks the farthest?

A) Tom
B) Juan
C) Alicia
D) Petra

Answer 1

To determine the student who walks the farthest, we need to calculate the distance each student walks. Alicia walks the farthest with a distance of 2.40 km.

Step-by-step explanation:

To determine which student walks the farthest, we need to calculate the distance each student walks. Distance is equal to speed multiplied by time. Tom walks for 25 minutes at a speed of 5.0 km/h, so his distance is 5.0 km/h * 25 min = 2.08 km. Juan walks for 22 minutes at a speed of 4.2 km/h, so his distance is 4.2 km/h * 22 min = 1.47 km. Alicia walks for 32 minutes at a speed of 4.5 km/h, so her distance is 4.5 km/h * 32 min = 2.40 km. Petra walks for 40 minutes at a speed of 3.5 km/h, so her distance is 3.5 km/h * 40 min = 2.33 km.

Therefore, the student who walks the farthest is Alicia with a distance of 2.40 km.
