A and B started from X and Y respectively at the same time in the opposite directions. After meeting, A took 2.7 hours to reach Y and B took 1.2 hours to reach X. If the speed of B is 48 km/h, what is the speed of A (in km/h)? |

Formula used , ( \(\frac{Speed\; of \;A }{Speed \;of \;B }\) )2 =\(\frac{Time\; taken \; by \;B}{Time\; taken \; by \;A}\) Le speed of A = A km/h (\(\frac{A}{48}\) )2= \(\frac{1.2}{2.7}\) A = \(\frac{2}{3}\) × 48 = 32 km/h So , Speed of A = 32 km/h |
