Complete question − How many kilometres did they travel by bus and by bicycle.
Answer:George and carmen traveled by bus in 135km and by bikein 215km
Step-by-step explanation:
Total Miles traveled = 350 miles
Let Number of kilometres they traveled with bus = x
and Let Number of kilometres they traveled with bike = x + 80
so that the total distance traveled with bus and bike be expressed as
x + x + 80 = 350 miles
2x + 80 = 350 miles
2x = 350 − 80
2x =270
x=135
George and Carmen traveled by bus in 135km
and by bicycle=x + 80 = 135 km + 80 =215km
