# If a car averages #50 1/3# miles per hour, how many hours will it take to go #47 1/2# miles?

##### 2 Answers

0.944 hrs, or 56 minutes, 36 secs.

#### Explanation:

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.

56.6 minutes.

#### Explanation:

distance = speed x time.

So in this problem distance =

speed =

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:

4 .d.p

Time in minutes:

56.6 minutes.
