A coach noted these stroke rates for rowing crews of eight. Calculate each stroke rate per minute, to
the nearest tenth. Then order the stroke rates per
minute, from least to greatest.
a) 195 strokes in 6 min
b) 181 strokes in 5 min
c) 214 strokes in 7 min

2. Coaches compare rowing speeds by calculating the distance per
second. Calculate the speed in each situation, to the nearest tenth of
a meter per second.
a) A crew of eight in a men’s race rowed 2000 m in 5:35.98. (The
time 5:35.98 means 5 min 35.98 s.)
b) A crew of four in a women’s race rowed 2000 m in 6:31.40.
c) A single rower in a men’s single scull rowed 2000 m in 7:06.76.

3. Why would the unit rates in questions 1 and 2 be useful for a coach?
