Mai runs a 400 meter track at a constant speed of 250 meters per minute. how many minutes does it take mai to complete 4 laps of the track?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
