Answer:
a)
0.8 hours
b)
1.1 kilometers/min
Step-by-step explanation:
a)
D = distance between town A and town B = 45 kilometers
v = speed of the train traveling from town A to town B = 60 kilometers per hour
t = time taken for the train to travel from town A to town B
Time taken is given as
t = D/v
inserting the values
t = 45/60
t = 0.8 hours
b)
D = distance between town A and town B = 45 kilometers
v = speed of the train traveling from town A to town B = ?
t = time taken for the train to travel from town A to town B = 40 minutes
Speed of the train is given as
v = D/t
inserting the values
v = 45/40
v = 1.1 kilometers/min
Answer:
c) 3.5%
Step-by-step explanation:
First, determine the difference between their old and new salary:
$44,505 – $43,000 = $1,505
Next, divide the raise amount by the old salary:
$1,505 / $43,000 = . 035
To turn the decimal into a percentage, multiply by 100
0.35x100=3.5%
Number of gallons of gAS USED / WEEK = 150/25 = 6 gallons
