Explanation:
Detailed explanation-1: -Hence, the speed of the car is equal to 75 Km/hr and 20.83 m/s, respectively.
Detailed explanation-2: -∴speed required=1503=50 km per hour.
Detailed explanation-3: -Here we will learn the mathematical relation between the speed, distance and time. The speed of a moving body is the distance travelled by it in unit time. If the distance is in km and time is in hours, then the speed is km/hr. If the distance is in m and the time is in seconds, then the speed is m/sec.
Detailed explanation-4: -= 32 km/hr. Q. A car travels first 60 km in 2 hours and next 100 km in 3 hours. Find the average speed of the car.
