Two tourist buses start from the same point and move along two roads at right angles at speeds of 48 km/h and 36 km/h, respectively. the distance between the buses after 15 seconds is_______
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 250 m.
Speed = Distance/time
The total distance covered by Bus A in 15 sec = 48 × 5/18 × 15 = 200m
The total distance covered by Bus B in 15 sec = 36 × 5/18 × 15 = 150m
In right angle track :
H2 = 2002 + 1502
H2 = 62500
H = 250m
So, the distance between the buses = 250m
