Question

[100 Points] George and Carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 300 kilometers in total and they biked 70 kilometers more thands they were bussed. Let x= kilometers traveled by bike and y= kilometers traveled by bus. Findo how many kilometers they traveled by bike

Answer 1

ussed = x

biked = 75 + x

total trip = 325 = x + (75 + x)

325 = 75 + 2x

250 = 2x

x = 125

biked = 75 + x = 75 + 125 = 200 km

Answer 2

ussed = x
biked = 75 + x

total trip = 325 = x + (75 + x)
325 = 75 + 2x
250 = 2x
x = 125

biked = 75 + x = 75 + 125 = 200 km
