Darnells car used 8 gallons of gasoline to to travel 340 miles a mican
so, he gets 340/8 mi/gal
The ratio of dogs and cats at the pets store is 2:5 if there are 6 more cats than dogs, how many dogs are in the pet store
d/c = 2/5
That is, 5d = 2c
Now, c = d+6
so, 2c = 2d+12
5d = 2d + 12
3d = 12
d = 4
check: 4 dogs, 10 cats
4:10 = 2:5 and 10 = 4+6
To calculate the miles per gallon (MPG) for Darnell's car, you need to divide the number of miles traveled by the amount of gasoline used. In this case, Darnell's car traveled 340 miles and used 8 gallons of gasoline.
To calculate the MPG:
1. Divide the number of miles traveled by the amount of gasoline used:
MPG = miles / gallons
MPG = 340 miles / 8 gallons
2. Solve the equation:
MPG = 42.5 miles per gallon
Therefore, Darnell's car has a fuel efficiency of 42.5 miles per gallon.
