Answer:
2,11,200 feet per hour
Step-by-step explanation:
Given: A dolphin can swim up to 40 miles per hour.
To Find: speed of dolphin in feet per hour.
Solution:
speed of dolphin \(=40\) \(\text{miles per hour}\)
Now,
\(1\text{mile}\) \(=5280\text{feet}\)
Number of miles traveled by dolphin in \(1\text{hour}\)
\(=40\text{miles}\)
converting speed from miles to feet
\(1\text{mile}\) \(=5280\text{feet}\)
\(40\text{miles}=5280\times40\)
\(2,11,200\) \(\text{feet}\)
speed of dolphin is \(2,11,200\) \(\text{feet per hour}\)
