Answer:
171.85 cm
Step-by-step explanation:
Given data
We are given that the distance = 149 cm 415in
Let us mark the units uniform by converting inches to cm
1 inches = 2.54cm
415 inches= x cm
cross multiply
x= 415*2.54
x= 1054.1 cm
Hence the total distance in cm is 1054.1+149= 1203cm
If in 7 days he travels 1203cm
in 1 day he will travel x cm
cross multiply
7x= 1203
divide both sides by 7
x= 1203/7
x= 171.85 cm
