Eunice runs around an oval quarter-mile track, completing one lap every 2 minutes and 30 seconds. At this speed, how many seconds will it take him to run a mile?

Respuesta :

I belive 600 seconds. I converted 30 seconds / 60 to decimal form which is .5
so you have 2.5 x 4 = 10 min/mile x 60 seconds = 600 seconds. I hope thats correct
