Question 1172908
<br>
In the 2 hours the jeep travels before the car starts, it travels 2*30 = 60 km.<br>
The difference in the speeds of the two vehicles is the rate at which the car overtakes the jeep, once the car starts.  That difference is 50 km/h.<br>
The time required for the car to overtake the jeep is the distance, divided by the difference in the speeds:<br>
60/50 = 1.2<br>
ANSWER: 1.2 hours<br>
