4) A snail has a top speed of 2.8 x 10-m/s. The earth has a circumference of 4 x 107 metres.
How long does it take a snail to crawl this distance. Give your answer in seconds and
to two significant figures.

The average speed of a snail is 0.02 mile/hr

Converting to S.I. units,

3600

0.02×1.6×1000

m/sec [1 mile =1.6 km =1600m]=0.0089m

−1

The average speed of leopard =70 miles/hr

In SI units=70 miles/hour=

3600

70×1.6×1000

=31 m/s.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
