Avinash travelled 42 km 365 m by bus, 12 km 460 m by car, and walked 640 m. How many kilometres did he travel altogether? (Write your answer in decimal fractions).
उत्तर
Distance travelled by bus = 42 km 365 m
= 42 km + 365 m
= 42 km + `365/1000`km .........(1 km = 1000 m)
= 42 km + 0.365 km
= 42.365 km
Distance travelled by car = 12 km 460 m
= 12 km + 460 m
= 12 km + `460/1000` km ........(1 km = 1000 m)
= 12 km + 0.460 km
= 12.460 km
Distance travelled by walked = 640 m
= 640 m
= `640/1000` km ........(1 km = 1000 m)
= 0.640 km
∴ Total distance travelled altogether
= Distance travelled by bus + Distance travelled by car + Distance travelled by walking
= 42.365 km + 12.460 km + 0.640 km
= 55.465 km
1 1
42.365
12.460
+ 0.640
55.465
Thus, the total distance travelled by Avinash altogether is 55.465 km.
