Answer:

$\pounds36$

Step-by-step explanation:

Cost of one dress = $\pounds40$

Cost of one pair of shoes = $\pounds32$

Cost of one dress and a pair of shoes is $40+32=\pounds72$

They get half off the price because they buy both

$\dfrac{72}{2}=\pounds32$

The shipping and handling charge is $\pounds4$ .

What is a speed of 55 mph equivalent to in units of m/s? ( 1 mile = 1609 m, 1 hour = 3600 s)

koban [17]

Answer:

about 24.58 m/s

Step-by-step explanation:

Multiply by conversion factors that change the units, but not the value.

(55 mi/h) × (1609 m/mi) × (1 h)/(3600 s) = (55×1609/3600) m/s

= 88495/3600 m/s ≈ 24.58 m/s

_____

<em>Additional comment</em>

The exact conversion uses 1609.344 meters per mile, so gives exactly 24.5872 m/s.
