Question

It takes a snail 500 hours to travel 15 miles. At this rate, how many

hours will it take the snail to travel 6 miles?
(1) 0.18 (3) 150
(2) 5.56 (4) 200

Answer 1

(4) 200

If you do:
15/500=0.03 m/h you find the miles travelled in 1 hour;
now you have 6 miles so you need to do:
6/0.03=200 hours

Answer 2

Option (4) 200 hours.

Explanation:

Time taken by a snail in travelling 15 miles = 500 hours

Therefore, time taken by the snail in travelling 1 mile =
`(500)/(15)`

Time taken by the snail to travel 6 miles =
`(500)/(15)* 6`

= 199.98 ≈ 200 hours

It will take the snail 200 hours to travel 6 miles.
