Two Towns A and B are 180 km apart car one and car two start travelling from A to B respectively towards Each Other their speeds are in the ratio 1 ratio 2 and they start at 7:00 a.m. to 8 a.m. respectively after meeting at C they returns to their starting position and again start travelling each other in order to meet car one for the second time at C car1 to halt at C for how much time does it halt
Answers
Answer:
Distance from the starting point after which both the cars will cross each other = (180 + 45) km = 225 km
Step-by-step explanation:
Given:
Speed of car A = 45 km/h
Speed of car B = 75 km/h
Distance between the initial and final point = 300 km
Here we need to calculate the time in which B reached the destination.
A will cover some distance in that time, and after that their speed will add up to give the relative speed and both the cars would meet after that point.
Formula used :
Speed = Distance/Time
Calculation :
Time taken by car B to travel 300 km
= (300/75) hr
= 4 hr
Distance traveled by car A in 4 hrs
= (45 × 4) km
= 180 km
The two cars will cross after 180 km.
Distance left to be traveled by car A = (300 - 180) km = 120 km
After 180 km, both the cars will travel in the opposite directions with respect to each other.
Relative speed of car A
w.r.t to car B = (45 + 75) km/h
= 120 km/h
Time after which both the cars will meet = (120/120) hr
= 1 hr
Distance traveled by car A in 1 hr = ( 45 × 1) km
= 45 km
Distance from the starting point after which both the cars will cross each other = (180 + 45) km = 225 km
