# How long does it take to drive 40 miles at 60 mph?

Speed, distance, and time are interconvertible formulas, thus, knowing any two values can be useful to calculate the remaining third value.

## Answer: The total time taken to cover 40 miles at 60 mph in 40 minutes.

The unit of speed is always in accordance with that of the time and distance.

**Explanation:**

Given, Distance = 40 miles, Speed = 60 mph

Speed = Distance / Time

⇒ 60 = 40 / Time

⇒Time = 40 / 60 hour

Time = 2 / 3 hour or 2 / 3 × 60 = 40 minutes. [ 1hour = 60 minutes ]
