If the average speed of a garden snail is 0.025 miles per hour and one inch is approximately 2.54 centimeters, how many minutes
2 answers:
Snail takes 1.5 minutes to travel around one meter
<u>Solution:</u>
Given, the average speed of a garden snail is 0.025 miles per hour
And one inch is approximately 2.54 centimeters,
We have to find how many minutes would it take a garden snail to travel one meter?
Now, let us convert the speed in miles per hour to meters per minute
Then, speed = 0.025 miles per hour
= 0.025 x 1 mile / 1 hour
= 0.025 x 1609.34 meters / 60 minutes
= 0.025 x 1609.34 / 60 meters per minute
= 0.670 meters per minute.
Now, 0.670 meters ⇒ 1 minute
Then, 1 meter ⇒ n minutes
So, by criss cross method
n x 0.67 = 1 x 1
n = 1.4912
Hence, snail takes 1.5 minutes approximately to travel 1 meter.
