Question

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

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

Answer 1

Part 1) 1,560 words

Part 2) 161 miles

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)

`(130)/(5)\ (words)/(min)= (x)/(60)\ (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

`(322)/(120)\ (miles)/(min)= (x)/(60)\ (miles)/(min)\\\\x=322(60)/120\\\\x=161\ miles`
