Answer:
The wheel will make 40 revolutions.
Step-by-step explanation:
We are given;
Diameter = 77 cm = 0.77m
Radius = 0.77/2
Radius = 0.385 m
Speed = 1.1 m/s
time = 1min 28 sec = 88 sec
Now, we know that;
Distance = speed×time
Thus;
Distance = 1.1 × 88
Distance = 96.8 m
Also,
Number of revolution = distance/circumference
Number of revolutions = 96.8/(2 × π × 0.385)
Number of revolutions ≈ 40
