Let's solve each of the three problems step by step. These are all related to
speed, which is calculated using the formula:
$$
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
$$
We'll use this formula for all three problems.

Problem 1:
Calculate the speed of a dog running through a backyard if it is covering 25.8 meters in 37 seconds.
####
Work:
$$
\text{Speed} = \frac{25.8 \text{ m}}{37 \text{ s}} = 0.6973 \text{ m/s}
$$
Rounded to the nearest hundredth:
$$
\text{Speed} ≈ 0.70 \text{ m/s}
$$
####
Answer:
$$
\boxed{0.70} \text{ m/s}
$$

Problem 2:
What is the speed of a sailboat that is traveling 110 meters in 135 seconds?
####
Work:
$$
\text{Speed} = \frac{110 \text{ m}}{135 \text{ s}} = 0.8148 \text{ m/s}
$$
Rounded to the nearest hundredth:
$$
\text{Speed} ≈ 0.81 \text{ m/s}
$$
####
Answer:
$$
\boxed{0.81} \text{ m/s}
$$

Problem 3:
Rebecca decided to calculate the speed of a tarantula that she saw at a museum. She found that the tarantula traveled 20 centimeters in 5 seconds. What was the average speed of the spider?
####
Work:
$$
\text{Speed} = \frac{20 \text{ cm}}{5 \text{ s}} = 4 \text{ cm/s}
$$
####
Answer:
$$
\boxed{4} \text{ cm/s}
$$
