Question

The odometer of a car reads 2000 km at the start of a trip and 2800 km at the end of the trip. If the trip takes 12 hours, calculate the average speed of the car in km/hr and m/s.

Answer 1

Answer:

Speed (km/hr) = 66.67 km/hr

Speed (m/s) = 1,111 m/s

Explanation:

Change in Distance = 800 km

Change in Time = 12 hrs

Speed (km/hr) = (800 km)/(12 hrs)    =>    Speed (km/hr) = 66.67 km/hr

Speed (m/s) = (66.67 km/hr)(1000 m/km)(1/60 hr/s)  =>  Speed (m/s) = 1,111 m/s
