Answer:
Step-by-step explanation:
GIVEN ;
Diameter = 77 cm
Radius = 77/2 × 1/100 m
= 0.385 m
Speed = 1.1 m/s
time = 1min 28 sec = 88 sec
Distance = speed×time
= 1.1×88
= 96.8 m
Number of revolution = distance/circumference
= 96.8/(2×22/7×0.385)
= 96.8×7/44×0.385
= 677.6/16.94
= 40
therefore the wheel will make 40 revolution.
