Respuesta :
The approximate location of the dolphin is 155 feet as it moves at the rate of 6.2 feet per second.
Rate in defined as the speed or the distance travelled by the dolphin in unit time.
- rate or speed is calculated by dividing the distance travelled by the total time taken to cover that distance.
- The units of rate is given by unit of distance/unit of time .
- The units of rate are meter/second , miles/hour , feet/second etc..
- Velocity is defined as the rate in a specified direction. Velocity is a vector quantity while speed or rate is a scalar quantity.
Given the rate of the dolphin is feet per second .
Time taken by the dolphin is 25 seconds.
∴ distance travelled is given by rate × time
Hence distance travelled is 6.2 × 25 = 155 feet
Therefore the approximate location is given by 155 feet from the starting point.
