Question

A car moves with a speed of 60km/hr for 20 minutes and then at a speed of 30km/h for next 20 minutes. The total distance covered by the car

Answer 1

Answer:

Speed 1= 60 km/h

Time 1= 20 mins

Speed 2= 30 km/h

Time 2 = 20 mins

Total speed = speed 1 + speed 2

= (60+30) km/h

= 90 km/h

Total time = Time 1 + time 2

= (20+20) mins

= 40 mins

Convert 40 mins into hour

40/60 = 0.666...h or 0.6 h

Total distance= total speed × total time taken

= 90 km/h × 0.6 h

= 54 km

Thus, the total distance is 54 km.
