Answer:
110beats/minutes
Step-by-step explanation:
we know we have 11 beats every 6 seconds,
that implies that there are 110 beats every 60seconds
and 60secs is a minute
that means 110beats/mins
the answer is 4 hours.
x: time clark drove
Y: Mitchells time drove
60 times Y = 75 times x
y=x+1
60(x+1)=75x
60x+60=75x
60=15x (subtract the 60x to the other side)
60/15=4
x=4
