A car moving with 6/9 of its actual speed covers 50 km in 1 hour 40 min. What is the actual speed of the car?

45 Km/hr

The ratio of actual speed and the current speed is 9 : 6 = 3 : 2

Time given = 1 hr. 40 min = 1 + \(\frac{2}{3}\) hrs. = \(\frac{5}{3}\) hrs.

Current speed = \(\frac{50 }{\frac{5}{3}}\) = 30 km/hr

Ratio- 3 : 2

2 stands for 30 km/hr, whereas, 3 becomes - 45 km/hr

Therefore, Actual speed of the car = 45 km/hr
