Both Runner A and Runner B have the same unit rate of 2.56 m/s, as they cover 64 meters in 25 seconds. Therefore, neither runner is faster than the other, and both will be 115.2 meters away from the starting point at 45 seconds.
To determine the unit rates for the two runners and decide which runner can run faster, we need to calculate each runner's speed in meters per second (m/s). The speed or unit rate is given by the formula:
According to the information provided, both Runner A and Runner B reach a distance of 64 meters at the same time of 25 seconds. Therefore, their speeds can be calculated as follows
Since both runners have the same speed of 2.56 m/s, neither runner is faster than the other. To predict how far each runner will be from the starting point at time t = 45 s, we simply multiply their speed by the desired time: Therefore, both Runner A and Runner B will be 115.2 meters away from the starting point at 45 seconds.
