Two Physics professors challenge each other to a 100 m race across the football field. Dr. Rice runs the race in 10.40 seconds. Dr. Lopez runs the first 25 2nd m with an average speed of 10 m/s, the next 50 m with an average speed of 9.50 m/s and the last 25 m with an average speed of 11.1 m/s.

Dr. Rice

Explanation:

For determining who is stuck grading physics labs  for the coming month first determine the Dr. De La Paz time taken

= (25 ÷ 10) + (50 ÷ 9.5) + (25 ÷ 11.1)

= 2.5 + 5.26 + 2.25

= 9.51 seconds

And, the Dr Rice runs the race is 10.40 seconds that means he takes more time as compared with the Dr. De La Paz

We simply applied the distance by speed formula so that the time could come

Therefore the  Dr. Rice gots stuck

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
