Question

Anbu and Mala travelled from A to C in two different routes. Anbu travelled from place A to place B and from there to place C. A is 8.3 km from B and B is 15.6 km from C. Mala travelled from place A to place D and from there to place C. D is 7.5 km from A and C is 16.9 km from D. Who travelled more and by how much distance?

Sum

Solution

Distance travelled by Anbu:

From place A to place B = 8.3 km

Distance from place B to place C = 15.6 km

∴ Total distance travelled by Anbu = 8.3 + 15.6

= 23.9 km

Distance travelled by Mala:

Distance travelled place A to D = 7.5 km

Distance from place D to place C = 16.9 km

Total distance travelled by mala = 7.5 + 16.9 km

= 24.4 km

24.4 > 23.9

∴ Mala travelled more distance.

She travelled 24.4 – 23.9 km more i.e she travelled 0.5 km more
