the speedometer reading of a car is shown. Find the distance travelled by the car in 20 minutes if the car is moving in uniform speed |
|
Answer» ONG>Explanation: The odometer of a CAR reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance MOVED by the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also. Answer Given Initial reading of odometer = 57321.0 km Final reading of odometer = 57336.0 km Initial Time = 8:30 AM Final Time = 8:50 AM We know that Odometer measure the distance travelled by the car So TOTAL distance covered by car= Final reading of odometer - Initial reading of odometer =57336.0 - 57321.0 = 15.0 km Total time taken by Car = Final Time - Initial Time =8:50 AM - 8:30 AM = 20 minutes= 20/60 hrs. = 1/3 hrs. Now Speed of the car is defined as = Total distance covered/Total time taken = 15.0/20 = 0.75 km/min Also Speed of the car in km/hr. =15/ (1/3) = 45 km/hr. |
