Question

The diameter of a car's tyre is 70 cm. Find the distance covered in 5 rounds. Find the number of turns required to cover a distance of 1540 m.

Answer 1

The number of turns required to cover a distance of 1540 m is 7

The distance covered in 5 rounds is 1100 m

Step-by-step explanation:

Diameter of car's tyre = 70 cm

Radius of car's tyre $= \frac{70}{2}= 35$

Distance covered in 1 round = $2 \pi r = 2 \times \frac{22}{7} \times 35=220 cm$

Distance covered in 5 round $= 220 \times 5 = 1100 m$

Number of rounds covered in 1100 m = 5

Number of rounds covered in 1 m =$\frac{5}{1100}$

Number of rounds covered in 1540 m =$\frac{5}{1100} \times 1540= 7$

Hence the number of turns required to cover a distance of 1540 m is 7

Answer 2

Answer:

The number of turns required to cover a distance of 1540 m is 7

The distance covered in 5 rounds is 1100 m

Step-by-step explanation:

Diameter of car's tyre = 70 cm

Radius of car's tyre = \frac{70}{2}= 35=270=35

Distance covered in 1 round = 2 \pi r = 2 \times \frac{22}{7} \times 35=220 cm2πr=2×722×35=220cm

Distance covered in 5 round = 220 \times 5 = 1100 m=220×5=1100m

Number of rounds covered in 1100 m = 5

Number of rounds covered in 1 m =\frac{5}{1100}11005

Number of rounds covered in 1540 m =\frac{5}{1100} \times 1540= 711005×1540=7

Hence the number of turns required to cover a distance of 1540 m is 7
