Question

To reach his office from home, David walks 1*1/
5 km and covers the remaining distance of 3*1/10 km to his office by taxi. How far is David's office from his home?

Express the answer as a mixed fraction.

Answer 1

Answer:

Distance travelled by David by walking = 1$\frac{1}{5}$ km = $\frac{6}{5}$ km

Remainig distance travelled by David    = 3$\frac{1}{10}$ km = $\frac{31}{10}$ km

Total distance between David's office and home = $\frac{6}{5}$ km + $\frac{31}{10}$ km

                                                 ⇒LCM of 10 and 5 = 10

                                                 ⇒ $\frac{12}{10\\}$ + $\frac{31}{10}$ km

                                                 ⇒ $\frac{43}{10}$ km                    

                                                 ⇒4$\frac{3}{10}$ km
