The acceleration of the fire truck is 1.666 m/s².
<u>Step-by-step explanation:</u>
Acceleration is the measure of change in velocity with respect to time. So as the initial velocity of the fire truck is given as 0 km/hr and the final velocity is given as 66 km/hr. So at first the truck is at rest and on switching on the engine, the truck gets to the velocity of 66 km/hr in 11 seconds.

But first the units of velocity should be changed from km/hr to m/s
1 hour = 3600 seconds
1 km = 1000 m
So, 
Converted Velocity = 18.33 m/s
Then, the acceleration will be

Acceleration = 1.666 m/s²
So, the acceleration of the fire truck is 1.666 m/s².
To find the unit rate of any two numbers you divide:
9.60 divided by 4 = 2.4
Unit rate = $2.40

Answer:
335.02
Step-by-step explanation:
Just multiply 23.93 by 14 which is 2 weeks
The amount Jake Hunter earned last week was $800.00
What is the total earnings of Jake Hunter for the week?
The total earnings of Jake Hunter for the week comprises of the regular rate multiplied the regular hours of 40 hours and the overtime rate, which is double of the regular pay multiplied by the overtime hours of 5 hours
Total earnings=($16*40)+($16*2*5)
2 means double of the regular pay of $16 , then multiplied by 5 overtime hours
Total earnings=$640+$160
Total earnings=$800.00
