To find the speed (v), we can divide the total distance traveled by the total time taken:
Total distance = l1 + l2 = 40 km + 45 km = 85 kmTotal time = t1 + t2 = 2 hours + 3 hours = 5 hours
Speed (v) = Total distance / Total timeSpeed (v) = 85 km / 5 hoursSpeed (v) = 17 km/h
Therefore, the speed of the object is 17 km/h.
To find the speed (v), we can divide the total distance traveled by the total time taken:
Total distance = l1 + l2 = 40 km + 45 km = 85 km
Total time = t1 + t2 = 2 hours + 3 hours = 5 hours
Speed (v) = Total distance / Total time
Speed (v) = 85 km / 5 hours
Speed (v) = 17 km/h
Therefore, the speed of the object is 17 km/h.
