Earth is approximately 9.3 × 107 miles from the sun. Saturn is approximately 8.87 × 108 miles from the sun. About how much farth

Lostsunrise [7]

First you get both distances
9.3 x 107 = 995.1 miles
8.87 x 108 = 957.96 miles
then you subtract them both
995.1 - 957.96 = 37.14 miles
and 37.14 miles is the distance between Earth and Saturn.

31.8 miles/hr= ? Feet/sec

PSYCHO15rus [73]

1 mi = 5280 ft
1 h = 3600 s

therefore:

$31.8\ \dfrac{mi}{h}=31.8\cdot\dfrac{5280}{3600}\ \dfrac{ft}{s}=46.64\ \dfrac{ft}{s}$

Answer: 31.8 mi/h = 46.64 ft/s
