Mr. Wu rides his bike at 6 mph to the bus station. He then rides the bus to work, averaging 30 mph.

If he spends 20 minutes less time on bus than on the bike, and the
distance from his house to work is 26 miles, what is the distance from
his house to bus station?

Fill out the information in the table for your convenience. Write the
equation. Solve. Show your work. Check your work

Answers

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

Answer:

40 feet

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

a² + 9² = 41²

a² + 81 = 1681

Subtract 81 from both sides

a² = 1600

Take the square root of both sides

a = 40

7x - 21 = 49

7x = 70

- Now divide each side by 7:

7x = 70

x = 10
