Step-by-step explanation:
a) First Distance = 5.673 kilometers
2nd distance = 4321 meters
Total distance = 1st distance + 2nd distance
Total distance = 5.673 kilometers + 4321 meters
Conversion from kilometers to meters:
1 kilometer = 1000meters
5.673 kilometers = 5673 meters
Total distance in meters = 5673 meters + 4321 meters
Total distance in meters = 9994 meters
Conversion of meters to hectometers:
100 meters = 1 hectometers
9994 meters = x
cross multiply:
100(x) = 9994(1)
100x = 1994
x = 1994/100
x = 19.94 hectometers
Hence, he rode 19.94 in hectometers
b) converting to decimeters:
It is easier to convert from meters to decimeters
0.1 meters = 1 decimeter
9994 meters = y
y(0.1) = 1(9994)
0.1y = 9994
y = 9994/
