First let us calculate for the total time of the travel
using the formula:
time = distance / velocity
time = 90 miles / 40 mph
time = 2.25 hours
Next, we calculate for the total gallons of fuel that is
theoretically required:
theoretical amount needed = 90 miles / 24 mpg
theoretical amount needed = 3.75 gallons
The difference of the actual and theoretical amount is the
amount which leaked:
amount leaked = 8 gallons – 3.75 gallons
amount leaked = 4.25 gallons
Therefore the amount of gallons leaked per hour is:
amount leaked per hour = 4.25 gallons / 2.25 hours
<span>amount leaked per hour = 1.89 gallons / hr</span>
Answer: b)
Step-by-step explanation:
Given,
speed of train A travelling east = 55 mph
speed of train B travelling west = 70 mph
time train A travelled while train B was at rest = 45 min or
so, Distance travelled by train A while train B was at rest =
=
Now, after 'T' hour both the train will travel;
train A = 55T
train B = 70T
hence, the distance (D) between two train in miles will be;
⇒ D = 41.25 + 55T + 70T
⇒ D = 125T + 41.25
Answer: 14.5
Step-by-step explanation:
If we divide 58x by 4, our answer would be 14 and a half. Which is same thing as 14.5.
= 58x/4
x = 14.5
Answer:
Combine like terms for the than you do to other side the multiply last for least you divide both sides
Step-by-step explanation:
The answer is b integers
