Answer» Answer: find the speed of the CAR between 12:00 HOURS to 12:30 hours time = 12:30 - 12:00 = 30 mins = 1/2 hr Distance = 65-30 = 35 km average speed = distance/ time taken = 35/(1/2) = 70 km/hr what is the average speed of the car total time = 1:00 pm = 13:00 - 11:00 = 2 hrs distance = 100 km speed = 100/2 = 50 km/ hr is the car's motion is an EXAMPLE of uniform motion No ist 1/2 hr 60 km/ hr 2nd 1/2 hr 0 km/ hr next 2 1/2 hrs 70 km/ hr Explanation: Please FOLLOW me and like please |
