Question

one athlete runs certain distance in 3 minutes 25 seconds and another athlete runs the same distance in 2 minutes 45 seconds .what is the time difference between them?

Answer 1

Answer:

40s

Step-by-step explanation:

t1 = 3m25s

t2=2m45s

So t1-t2

=3m25s - 2m45s

=180+25s - (120+45s)

=205s-165s

=40s

hope it helps

Answer 2

Given :

initial time ( t₁ ) = 3 m 25 s

We know that 1 m = 60 s

So : 3 m 25 s = 3 × 60 s + 25 s

                      = 180 s + 25 s

                      = 205 s

Final time ( t₂ ) = 2 m 45 s

1 m = 60 s

2 m 45 s ==> 2 × 60 s + 45 s

                  = 120 s + 45 s

                  = 165 s

Difference

Difference = 165 s - 125 s

                  = 40 s

$\boxed{\bf{40\:s}}$
