Answer 1

Answer:

1.042 × 10⁻³ m/s

Explanation:

average speed =  $\frac{total \space\ distance \space\ covered}{time \space\ taken}$

In this case,

• distance covered = 90 m,

• time taken = 24 hours = 24 × 60 = 1440 min = 1140 × 60 = 86400 s

Substituting these values into the formula:

average speed = $\frac{90}{86400}$

                          = 1.042 × 10⁻³ m/s

Answer 2

Answer:

3.75 meters per hour

Explanation:

$\boxed{\sf Speed = \dfrac{Distance}{Time}}$

Given:

• Distance = 90 meters
• Time = 24 hours

Substitute the given values into the formula to calculated the speed:

$\implies \sf Speed = \dfrac{90\:m}{24\:h}$

$\implies \sf Speed = 3.75\:m/h$

Therefore, the average speed of the snail is 3.75 meters per hour.

To calculate the speed in meters per minute, divide by 60:

$\implies \sf Speed = \dfrac{3.75\:m/h}{60}=0.0625\:m/min$

To calculate the speed in meters per second, divide by 60 again:

$\implies \sf Speed = \dfrac{0.0625\:m/min}{60}=0.001042\:m/s\:\:(4\:s.f.)$
