Answer 2

The speed of car is 79.2 km/hr.

Step-by-step explanation:

Consider the provided information.

The diameter of the wheel is 70 cm.

The distance cover in one revolution: πD

Where, D is the diameter of the wheel.

$\pi D=\frac{22}{7}\times70=220$

Wheel covers 220 cm in one revolution.

The distance cover in 1 second is: 220 cm×10 = 2200 cm.

We need to find the distance in km/hr.

So distance cover in 1 hr is: 2200 cm × 60 × 60 = 7,920,000 cm

Now, convert cm to km by dividing 7,920,000 with 100,000

$\frac{7,920,000 }{100,000} =79.2$

Hence, the speed of car is 79.2 km/hr.
