# What is the time taken to travel 7150 km with a speed of 780 km/hr?

Mar 15, 2018

$\text{9.17 hr}$

#### Explanation:

With distance over speed, divide $7150$ by $780$ to get $9.17$.

Since $7150$ is in $\text{km}$ and $780$ is in $\text{km/hr}$ we cancel $\text{km}$

$\text{7150 km"/"780 km/h" = "9.17 hr}$

You may follow the triangle formula in which distance is at the top while speed or velocity and time are at the bottom.

If you are looking for distance:

$\text{Distance" = "Speed" xx "Time }$

If you're looking for speed or velocity:

$\text{Speed" = "Distance"/"Time}$

If you're looking for Time:

$\text{Time" = "Distance"/"Speed}$
