Question

A garden is 12 yards long. assuming the snail moves at a constant speed, how many minutes does it take the snail to travel the length of the garden? Speed: 5^(-5)feet per second

Answer 1

15 minutes, first you need to convert everything to feet, 3yards in a foot so multiply 12 by 3 and you get 36ft, 5^-2 is 0.04, so the snail goes 0.04ft every second. Divide 36 by 0.04 to get 900, that’s the distance and if he moves like that every second then that’s also the time, divide 900 by 60 to get minutes.

Answer 2

Using the formula of speed, the snail takes 15 minutes to travel the length of the garden.

What is the formula of speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time.

$Speed = \frac{Distance}{Time}$

Distance = 12 yards = 12 x 3 = 36 feet

Speed = $5^{-2}$ feet/second = 1/25 feet/second

$Time = \frac{Distance}{Speed} = \frac{36}{\frac{1}{25} } = 36*25 = 900 s$

Time taken by the snail to travel the length of the garden = 900s = 15 minutes.
