In a marathon of 5.75 km, you halted to drink water after running 2.8 km, After another 1.3 km, you again stopped to drink water. How many kilometres are yet to go?
1.65 km
Distance travelled before first halt = 2.8 km
Distance travelled before second halt but after first halt = 1.3 km
Hence, total distance covered before second halt
= (2.8 + 1.3) km = 4.1 km
Therefore, distance left
= Total distance - Total distance covered before second halt
= (5.75 - 4.10) km = 1.65 km
