(Time and Distance) Ajit can ride a scooter constantly at a speed of `30 kms/hour.` Draw a time-distance graph for this situation. Use it to find (i) the time taken by Ajit to ride `75km.` (ii) the distance covered by Ajit in `3 (1/2)` hours.

Explanation

To solve the problem step by step, we will first plot the time-distance graph for Ajit's scooter ride and then use it to answer the two parts of the question.

### Step 1: Calculate Distance for Different Times
We know that distance = speed × time. Given that Ajit's speed is 30 km/h, we can calculate the distance for different time intervals:
- For 0 hours: Distance = 30 km/h × 0 h = 0 km
- For 1 hour: Distance = 30 km/h × 1 h = 30 km
- For 2 hours: Distance = 30 km/h × 2 h = 60 km
- For 3 hours: Distance = 30 km/h × 3 h = 90 km
