Question : 23

Total: 40

2\;\frac{1}{2}

Solution:

Concept:

Distance is calculated using the relation: Distance = Speed × Time.

Explanation:

Given speed is

60

km per hour.

Given time is

2\;\frac{1}{2}

hours.

Convert the mixed fraction to an improper fraction:

2\;\frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2}

hours.

Now apply the formula:

Distance

= 60 \times \frac{5}{2}

km.

Simplify:

60 \div 2 = 30

So, Distance

= 30 \times 5 = 150

km.

Answer:

The car travels

150

km in

2\;\frac{1}{2}

hours.

Therefore, the correct option is D.

150

km.
