Answer 1

Answer:

Part 1) 1,560 words

Part 2) 161 miles

Step-by-step explanation:

Part 1) 130 words in 5 mins. How many words in an hour?

Remember that

$1\ hour=60\ min$

so

using proportion

Find out how many words in 60 minutes (one hour)

$\frac{130}{5}\ \frac{words}{min}= \frac{x}{60}\ \frac{words}{min}\\\\x=130(60)/5\\\\x=1,560\ words$

Part 2) 322 miles in 2 hours. How many miles in 60 minutes?

Remember that

$1\ hour=60\ min$

so

$2\ hours=120\ minutes$

using proportion

Find out how many miles in 60 minutes

$\frac{322}{120}\ \frac{miles}{min}= \frac{x}{60}\ \frac{miles}{min}\\\\x=322(60)/120\\\\x=161\ miles$
