You are leaving for a party at your cousin’s house in a city that is 150 km away. you will travel at an average rate of 50 km/hr. if you need to be at the party in 2.5 hours, how fast would you need to drive to get there?

If you travel at a constant rate, the equation which describes your traveling is

where s is the space traveled, v the velocity you're traveling at, and t is the time passed traveling.

You know the distance and the time, so let's solve the equation for speed:

So, if you plug the values, you have

So, you need to travel at an average speed of 60km/hr to be at the party in 2.5 hours. If you travel at an average speed of 50km/hr, you'll be there in three hours
