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 [tex]=40[/tex] [tex]\text{miles per hour}[/tex]
Now,
[tex]1\text{mile}[/tex] [tex]=5280\text{feet}[/tex]
Number of miles traveled by dolphin in [tex]1\text{hour}[/tex]
[tex]=40\text{miles}[/tex]
converting speed from miles to feet
[tex]1\text{mile}[/tex] [tex]=5280\text{feet}[/tex]
[tex]40\text{miles}=5280\times40[/tex]
[tex]2,11,200[/tex] [tex]\text{feet}[/tex]
speed of dolphin is [tex]2,11,200[/tex] [tex]\text{feet per hour}[/tex]
