Find the average speed of an objects it covers 25cm in 5 minutes​

Answer»

o find the average speed for the car to cover the distance of 5 km, we will divide the value of the distance by that of the TIME travelled, now to find the velocity in TERMS of km/hr, we NEED to convert the time from minute to hour by dividing it by 60 and the formula for the speed is:Speed = DistanceTimeComplete step by step answer:The distance travelled by the car in km is GIVEN as 5 km.The time taken to cover the distance of 5 kmis 5 min.Now to convert the time from minute to hour is given by dividing the minute value by 60. Hence, the minute value is:⇒560=112hNow using the time, distance and speed formula, we find the value of the speed in terms of km/hr as:Speed = DistanceTimePlacing the value of distance and time in the above formula, we get the value of the speed as:⇒Speed = 5 km112hr∴Speed = 60 km/hrTherefore, the value of the speed of the car moving a distance of 5 km is given as 60 km/hr.Note:Another method to find the speed is by CONVERTING the distance from 5km to 5000m and time from minute to seconds as 5min to 5×60=300 seconds, then using the formula of the speed and its value as:Speed = DistanceTimePlacing the value of distance and time as 5000m and 5min respectively. The value of the speed in terms of m/sec is:Speed = 5000300⇒Speed = 5000300 m/sNow to find the speed in terms of km/h from m/s, we will multiply the speed by 185 to get the speed in terms of km/h unit.⇒Speed = 5000300×185⇒Speed = 60 km/hr===============================Answer By shreyash
