Joseph drove for 3 hours at the speed of 40 km/h (kilometers

per hour). He changed his speed to 65 km/h for the next 2

hours. How far had Joseph driven in km?

250 km.

Step-by-step explanation:

Alright, so for this problem we can split it into two parts. Since distance = speed*time, the first 3 hours give us 3*40 or 120 km, and the last 2 hours give us 2*65, or 130 km. Adding these together, we get a final distance of 250 km.
