Question

During a 5 km walk to raise money for the school band, Tabitha walked at a pace of 0.08 of a kilometer per minute. Using 1 mi = 1.61 km, what was Tabitha's approximate pace in miles per hour?

Answer 1

To determine her miles per hour, you will first convert her pace of 0.08 commoners per minute to a number of kilometers per hour.

0.08 x 60 = 4.8 km per hour

Next convert her rate of 4.8 commoners per hour to a number of miles per hour.

4.8/1.61 = 2.99 Miles per hour

Tabitha walks approximately 3 mph.

Answer 2

We know that

1 mi -----------------> 1.61 km
 X--------------------> 0.08 km
X=0.08/1.61------------> 0.0497 mi/min

1 hour--------------> 60 min
X----------------------> 1 min
X=1/60--------> X=1/60 hour
so

0.0497 mi/min---------> 0.0497 /(1/60)------> 0.0497*60------> 2.98 mi/hour

the answer is
2.98 mi/hour
