...Hey Dear,

◆ Answer -

Time taken = 2.5 hrs

● Explanation -

# Given -

Initial odometer reading = 1500 km

Final odometer reading = 1750 km

Average velocity = 200/π km/h

# Solution -

Total distance covered by the car is given as -

Distance = final reading - initial reading

Distance = 1750 - 1500

Distance = 250 km

This distance is equal to half circumference of circle, thus -

Distance = π × radius

250 = π × radius

Radius = 250/π km

Displacement in semicircle is just the diameter of the circle, thus

Displacement = 2 × radius

Displacement = 2 × 250/π

Displacement = 500/π km

Time taken by the car to travel this distance -

Time = displacement / velocity

Time = (500/π) / (200/π)

Time = 500/200

Time = 2.5 hrs

Therefore, 2.5 hrs will be taken by the car to cover this distance.

Thanks dear

Answer -

Time taken = 2.5 hrs

Explanation -

Initial odometer reading = 1500 km

Final odometer reading = 1750 km

Average velocity = 200/π km/h

Total distance covered by the car is given as -

Distance = final reading - initial reading

= 1750 - 1500

= 250 km

This distance is equal to half circumference of circle, thus -

Distance = π × radius

250 = π × radius

Radius = 250/π km

Displacement in semicircle is just the diameter of the circle, thus

Displacement = 2 × radius

= 2 × 250/π

= 500/π km

Time taken by the car to travel this distance -

Time = displacement / velocity

= (500/π) / (200/π)

= 500/200

= 2.5 hrs

Therefore, 2.5 hrs will be taken by the car to cover this distance.
