# Going 40 miles an hour how long would it take me to go 60 miles?

Feb 26, 2018

$1 \frac{1}{2}$ hours

#### Explanation:

Distance traveled is equal to speed multiplied by time:

$d = s t$

Where $d$ is distance traveled, $s$ is the speed, and $t$ is the time (here, it will be in hours, as we're using miles per hour).

Plugging in our distance and speed, we get:

$60 = 40 t$

$t = \frac{60}{40} = \frac{6}{4} = \frac{3}{2}$ hours, or $1 \frac{1}{2}$ hours

$90$ minutes $\left(\text{1.5 hrs}\right)$

#### Explanation:

If you are travelling at $\text{40 mph}$, then it will take $30$ minutes to go $20$ miles and $60$ minutes to go $40$ miles. Thus, it will take $90$ minutes to go $60$ miles.

Alternatively:

"Speed"("mph")= ("Distance"("miles"))/("time"("hours"))

$40 = \frac{60}{t}$

$t = \text{1.5 hours}$
