(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:

Option (4) 200 hours.

Step-by-step explanation:

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

Therefore, time taken by the snail in travelling 1 mile = \(\frac{500}{15}\)

Time taken by the snail to travel 6 miles =  \(\frac{500}{15}\times 6\)                                                                                      

                                                                   = 199.98 ≈ 200 hours

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