If a car averages #50 1/3# miles per hour, how many hours will it take to go #47 1/2# miles?
0.944 hrs, or 56 minutes, 36 secs.
Best math teacher I ever had said: "Memorize as little as possible in mathematics." Words to live by.
One thing you SHOULD remember is that
Distance = rate x time.
You're given 2 of these, and so can solve for the other.
distance = speed x time.
So in this problem distance =
These have just been converted to improper fractions, this makes it easier when solving equations.
So we have:
Solving for t:
Multiply both sides by 3:
Multiply both sides by 2:
Divide both sides by 302:
Time in minutes:
