a student walks 180m in 155s. the student stops for 35s and then walks 320m farther in 145s. What is the average speed of the entire walk?

he walked 180+320 m

time elapsed: 155+35+145 s

avg speed= distance/time elapsed

1.49 m/s

To find the average speed of the entire walk, we need to calculate the total distance traveled and the total time taken.

First, we find the total distance traveled by adding the individual distances: 180m + 320m = 500m.

Next, we find the total time taken by adding the individual times: 155s + 35s + 145s = 335s.

Now, we can calculate the average speed by dividing the total distance by the total time: 500m / 335s.

Using a calculator or performing the division, we find that the average speed of the entire walk is approximately 1.4925 m/s.
