Type	multiple_choice
Option	65 km/hr	incorrect
Option	70 km/hr	incorrect
Option	45 km/hr	correct
Option	80 km/hr	incorrect

Solution:

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
