Answer 1

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

Answer 2

The answer to your question is 450 km

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
