A dolphin swam 12 miles in 4 hours. what was its average speed in miles per hour (mph) ? PLEASE HEL

The dolphin's average speed is 3 mph

Step-by-step explanation: The basic equation is Speed = Distance ÷ Time

S = d/t

To find miles per hour, divide the distance in miles by the time in hours.

Speed = 12 miles/4 hours .  12÷4 = 3

Speed = 3 mph
