= 8 hours 20 minutes
Rachael was gone for 8 hours 20 minutes

Step-by-step explanation:
1 revolution is equivalent to the circumference of the wheel
1 revolution = πd ( d is the diameter )
= 70π cm
50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )
so first find the 1/3 *5*5*5
this equals 41 and 2/3
so check if 41 and 2/3 *2 is greater than 50 which it is.
so the answr I h≤1
