Question

It is now 10:29
a.m., but when the bell rings at 10:30
a.m. suzette will be late for french class for the third time this week. she must get from one side of the school to the other by hurrying down three different hallways. she runs down the first hallway, a distance of 35.0 m, at a speed of 3.50 m/s. the second hallway is filled with students, and she covers its 48.0 m length at an average speed of 1.20 m/s. the final hallway is empty, and suzette sprints its 60.0 m length at a speed of 5.00 m/s.

Answer 1

I believe this question asks if Suzette will make it on time. From 10:29 am to 10:30 am, she only has 1 minute or 60 seconds to spare.

Calculating all the times:

35 m / (3.5 m/s) = 10 s

48 m / (1.2 m/s) = 40 s

60 m / (5 m/s) = 12 s

So total time is = 62 s

Hence Suzette will be late by 2 seconds.
