1 answer:
Answer: a. 126.20 gallons.
b. 2740 miles.
Step-by-step explanation:
We will use unitary method in this question.
a) ∵ 310 miles can be covered by a car with the help of 15.5 gallons of gasoline
∴ 1 mile can be covered = gallons
∴2524 miles can be covered =
= 126.20 gallons
b). ∵ With 15.5 gallons of gasoline car can be driven = 310 miles
∴ With 1 gallon of gasoline car can go = 310/15.5 miles
∴ With 137 gallons can can go = (310×137)/15.5 miles
= 2740 miles.

Step-by-step explanation:
Data provided in the question:
4e²ˣ⁻¹ -1 = 5
now solving for 'x'
⇒ 4e²ˣ⁻¹ = 5 + 1
or
⇒ 4e²ˣ⁻¹ = 6
or
⇒
or
⇒
now,
taking natural log both sides, we get
⇒ 2x - 1 =
also,
we know
⇒
thus,
⇒ 2x - 1 = ln(3) - ln(2)
or
⇒ 2x - 1 = 1.0986 - 0.6931
or
⇒ 2x - 1 = 0.4055
or
⇒ 2x = 0.4055 + 1
or
⇒ 2x = 1.4055
or
⇒ x = 0.70275
