Option | 65 km/hr | incorrect |
Option | 70 km/hr | incorrect |
Option | 45 km/hr | correct |
Option | 80 km/hr | incorrect |
Let the actual speed of the car = X km/hr
∴ the car is moving at X *6⁄9km/hr
Distance = 50 km
Time taken to cover 50 km= 1 hour 40 minutes →1+40⁄60= 5/3 hrs
Distance = Speed x Time
50 = X *6⁄9*5⁄3
