Dear Student!

Here is the answer to your question.

Distance traveled by the car = 90 km

Time taken by the car = $2 \frac{1}{2}$ hours = 2 hours + 30 minutes = 120 minutes + 30 minutes = 150 minutes

Speed of the car = $\frac{D i s \tan c e t r a v e l e d}{T i m e t a k e n} = \frac{90}{150} = \frac{3}{5} k m / \min$

Time taken by the car to travel 30 km = $\frac{D i s \tan c e}{s p e e d} = \frac{30}{(\frac{3}{5})} = \frac{30 \times 5}{3} = 50 \min u t e s$

Distance traveled by the car in 2 hours or 120 minutes = Speed × Time = $\frac{3}{5} \times 120 = 72 k m$

Cheers!
