Answer 1

$\huge {\blue {\underline {\underline {\bf {Answer :}}}}}$

In case 1 :

distance = 144 km

time = 3 hrs

so , speed = dis/time = 144/3 = 48 km/hr .

In case 2 :

distance = 240 km

speed = 48 km/hr ....... speed is same in both cases .

Time = ??

Time = dis/speed = 240/48 = 5 hrs .

So the answer is 5 hours .

• v = u + at

• ${\bf {s = ut + \frac {1}{2}at^2}}$

• ${\bf {v^2 = u^2 + 2as}}$
