The formula for the time it takes to travel a distance of d at an average speed v is (d)/(v). Tessa ran a 100-meter dash at a speed of about 7.5 meters per second. What calculation will give us the estimated duration of Tessa's dash in seconds? Choose 1 answer: (A) (7.5)/(100) (B) (100)/(7.5) (C) (7.5)/(100*60) (D) (100*60)/(7.5)

Formula Explanation: To find the time it takes to travel a certain distance at a given speed, we use the formula $t = \frac{d}{v}$, where $t$ is the time in seconds, $d$ is the distance in meters, and $v$ is the speed in meters per second. In this case, $d = 100$ meters and $v = 7.5$ meters per second.Substitution Step: Substitute the given values into the formula to calculate the time: $t = \frac{100}{7.5}$.Division Calculation: Perform the division to find the time: $t = 13.33$ seconds. This calculation gives us the estimated duration of Tessa's dash in seconds.

Formula Explanation: To find the time it takes to travel a certain distance at a given speed, we use the formula $t = \frac{d}{v}$ , where $t$ is the time in seconds, $d$ is the distance in meters, and $v$ is the speed in meters per second. In this case, $d = 100$ meters and $v = 7.5$ meters per second.
Substitution Step: Substitute the given values into the formula to calculate the time: $t = \frac{100}{7.5}$ .
Division Calculation: Perform the division to find the time: $t = 13.33$ seconds. This calculation gives us the estimated duration of Tessa's dash in seconds.
