Joy travelled a distance of five and two tenths of a kilometer in his journey by train and a distance of twenty one hundredth of a kilometer by car. The total distance(in km) covered by Joy is

Answer 1

Distance covered by Joy in train
= 5 km + $(\frac{2}{10}{)}^{th}$ km
= 5 km + 0.2 km = 5.2 km
Distance covered by Joy in car
= $(\frac{21}{100}{)}^{th}$ km = 0.21 km
$\therefore$ Total distance covered by Joy
= 5.2 km + 0.21 km = 5.41 km
