Question

bhanu drives his car at a speed of 70kmph how much distance will he cover in 3 hours 15 minutes

Answer 1

        Speed=70 kmph = 70 x 5/18 m/s = 19.4 m/s

Time=3hrs15min= 3x60x60+15x60 =10800+900=11700 sec

Distance = Speed x Time

   =70x(5/18)x11700

   =350*650

   =227500 m

Answer 2

speed=distance
$speed \: = \frac{distance}{time} \: \: so \\ distance = speed \: \times time$
$= distance = 70km \times 3h \: 15m \\ = distance = 70 \times 195 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 13650km$
bhanu will travel 13,650km in 3h 15m
