Answer 2

To calculate the distance traveled (S) for each vehicle given their respective speeds (V1 and V2) and time traveled (t1 and t3), you can use the formula:

$S = \text{speed} \times \text{time}$

Given speeds and times:

$V1 = 45 \text{ km/h}$ (speed of vehicle 1)

$V2 = 65 \text{ km/h}$ (speed of vehicle 2)

$t1 = 4 \text{ hours}$ (time for vehicle 1)

$t3 = 3 \text{ hours}$ (time for vehicle 2)

Let's calculate the distances for each vehicle:

1. Distance traveled by vehicle 1 (S1):

$S1 = V1 \times t1$ $S1 = 45 \, \text{km/h} \times 4 \, \text{hours}$ $S1 = 180 \, \text{km}$

2. Distance traveled by vehicle 2 (S2):

$S2 = V2 \times t3$ $S2 = 65 \, \text{km/h} \times 3 \, \text{hours}$ $S2 = 195 \, \text{km}$

So, the distances traveled by vehicle 1 and vehicle 2 are:

• Distance traveled by vehicle 1 (S1): $S1 = 180 \, \text{km}$
• Distance traveled by vehicle 2 (S2): $S2 = 195 \, \text{km}$
