Answer:
5305.1647 times
Step-by-step explanation:
The Circumference of a circle : πd
d = diameter of circle = 30 cm
Circumference of wheel = π * 30cm = 94.247779 cm
1km to cm
1km = 100000cm
5 km = 500000 cm
Hence, number of times wheel rotate on a 5km journey :
500000 cm / 94.247779 cm
= 5305.1647 times
i believe it is the first answer.
hope this helps my dude :- )
