Their relative speed is the sum of 60 and 40 or 100km/hr. They will travel the 150km in 1.5 hrs.<span>When two object approach each other, the closing speed is just the sum of the speeds, therefore, the closing speed is your case is 100kph. </span>
<span>Just take the distance of 150 km and divide by 100 to get 1.5 hours </span>
<span>checking: </span>
<span>the car going 60 will have traveled 60*1.5 = 90 km </span>
<span>the car going 40 will have traveled 40*1.5 = 60 km </span>
<span>the sum of the distances = 90+60 = 1.5 hours </span>
<span>So they will meet in 1.5 hours.</span>
