the distance between Nick and Sara's house is 546m. Nick can walk 1.3 m/sec. Using the formula d=rt, where d is distance, r is rate, and t is time, how long does it take Nick to get to sara's house in minutes?

Respuesta :

d=rt and we are told d=546 and r=1.3m/s so

1.3t=546  divide both sides by 1.3

t=420 seconds so

420s(min/60s)=7 min

So it takes him 7 minutes to walk to Sara's house.
