Question

Two physics professors challenge each other to a 100. m race across the football field. The loser will grade the winner's physics labs for one month. Dr. Rice runs the race in 10.40 s. Dr. De La Paz runs the first 25.0 m with an average speed of 10.0 m/s, the next 50.0 m with an average speed of 9.50 m/s, and the last 25.0 m with an average speed of 11.1 m/s. Who gets stuck grading physics labs for the next month?

Answer 1

Answer:

A delay by approximately 1 sec has resulted in Dr Rice getting stuck grading physics labs for a month! Guess what physics professors should stay away from physical games!

NB Last heard Dr Paz is practicing with Usain Bolt in the free time that he has got

Step-by-step explanation:

let's calculate Dr De La Paz's time. I have a hunch that this guy will be faster!

Anyways the Time taken is

$\frac{25}{10} + \frac{50}{9.50} + \frac{25}{11.1} = 2.5 + 5.26 + 2.25$

$= 9.51 \: secs$
