For a track meet, Tara ran the 1,600 m event at constant speed in 5 minutes and 20 seconds. What was her speed?
Arlecino [84]

Distance ran by Tara = 1600 m

Time taken by Tara to ran 1600 m = 5 min 20 seconds

We have to calculate the speed.

Firstly, we will convert the unit of time in one unit.

Time = 5 min 20 seconds

= 5 min +\frac{20}{60} min (Because 1 min = 60 sec)

= 5+\frac{1}{3}

=\frac{15+1}{3}

=\frac{16}{3} min

Now we will use Distance speed formula which states,

Distance = speed \times time

1600 m = speed \times \frac{16}{3}

speed = \frac{1600 \times 3}{16}

Speed = 300 m/min

So, the speed of Tara was 300 meter/min.
