A physicist wants to study the motion of a car.

a. The physicist put 8 L of gasoline in a ca. How many gallons is this? (Note: 1 gal = 3.79 L)

b. The car was able to travel 75.3 jm before it ran out of gas. How many miles is this? (Note 1 mi = 1.61 km)

c. The scientist put more gasoline in the car, and it was able to travel 38.1 miles. How many meters is this? (Note 1 mi = 1.61 km; 1000 m = 1 km)

a.
If 1 gal = 3.79L
then x gallons = (8 ÷ 3.79)
x is approximately 2.11 gallons

b.
If 1mi = 1.61km
then x miles = (75.3 ÷ 1.61)
x is approximately 46.77 miles

c.
If 1mi = 1.61km and 1km = 1000m, it implies that 1mi = (1.61 × 1000)meters
this is equal to 1610meters
since 1mi = 1610m, x meters = (38.1 × 1610)
x is 61341 meters.
