Final answer:
The grasshopper covers approximately 0.55 yards per hop when it covers 5 yards in 9 hops.
Step-by-step explanation:
To find out how many yards the grasshopper covers on each hop, divide the total distance covered by the number of hops. If the grasshopper covered 5 yards in 9 hops, you need to divide 5 yards by 9 hops.
5 yards ÷ 9 hops = 0.555... yards per hop
When you round this number to two decimal places, you get approximately 0.56 yards per hop. However, looking at the answer choices provided, the closest match is 0.55 yards per hop, which corresponds to option (b).
