Answer:
Step-by-step explanation:
2.3*10'-2
Answer:
26 mi
Step-by-step explanation:
Convert 20 min to hrs: 20/60 = 1/3 hr
:
Let t = time on the bike
then
t-(1/3) = time on the bus
:
Write a dist equation Dist = speed * time:
:
Bike dist + bus dist = 26 mi
6t + 30[t-(1/3)] = 26
:
6t + 30t - 10 = 26
36t = 26 + 10
36t = 36
t = 1 hr on the bike
:
6 mph for 1 h = 6 mi from house to the bus station
:
:
Check solution by finding the distance
6(1) + 30(2/3) =
6 + 20 = 26 mi
The small and large triangles are similar
so 3 / (3+3) = 9 / AC
9 / AC = 1/2
#AC = 18 ft Answer
