1. **Problem 1: Calculate the speed in Km/h of a runner who runs 100 m in 9.58 s.** 2. The formula for speed is $$V = \frac{e}{t}$$ where $e$ is distance and $t$ is time. 3. First, convert 100 meters to kilometers: $$100\,m = \frac{100}{1000} = 0.1\,km$$ 4. Convert 9.58 seconds to hours: $$9.58\,s = \frac{9.58}{3600} \approx 0.00266\,h$$ 5. Now calculate speed: $$V = \frac{0.1}{0.00266} \approx 37.59\,km/h$$ --- 1. **Problem 2: Calculate the distance Victor swam if he swam for 58 minutes at 1.5 Km/h.** 2. The formula for distance is $$e = V \times t$$ where $V$ is speed and $t$ is time. 3. Convert 58 minutes to hours: $$58\,min = \frac{58}{60} \approx 0.9667\,h$$ 4. Calculate distance: $$e = 1.5 \times 0.9667 = 1.45\,km$$ --- 1. **Problem 3: Calculate the time a car takes to travel 14 Km at 50 Km/h.** 2. The formula for time is $$t = \frac{e}{V}$$ where $e$ is distance and $V$ is speed. 3. Calculate time: $$t = \frac{14}{50} = 0.28\,h$$ 4. To convert hours to minutes: $$0.28 \times 60 = 16.8\,minutes$$ --- These steps show how to convert units properly and apply the basic kinematic formulas for uniform motion (MRU). Always remember to keep units consistent before calculating.
