Joseph drove for hours at the speed of 40 km per hours he changed his speed to 65 km for the next 2 hours how far had Joseph driven in km

The answer to your question is 450 km

Step-by-step explanation:

Data

First stage Second stage

speed 1 = 40 km/h speed 2 = 65 km/h

time 1 = 8 h time 2 = 2 h

Process

1. - Write the formula to calculate the speed

speed = distance / time

-Solve for distance

distance = speed x time

2. - Calculate the distance of the first stage

distance 1 = 40 x 8

distance 1 = 320 km

3. - Calculate the distance of the second stage

distance 2 = 65 x 2

distance 2 = 130 km

4. - Calculate the total distance

Total distance = 320 + 130

= 450 km

I'd go with the answer from the top it seems reliable
