Question

A boy takes 10 minutes to walk from his house to the bus stop. If his average working speed is 4 km/h, estimate the distance of bus stop from the house. a) 886 m b) 666.6 m c) 456.4 m d) 500m *

Answer 1

Answer:

There are 60 minutes in one hour,that means that 10 minutes is equal to 1/6 of an hour. Since you’re trying to find out distance and you know both speed and time you can use the equation:speed = distance /time, to isolate distance, multiply by time as multiplication is the inverse operation of division. Substituting that values the equation becomes distance = 1/6 hour • 4 km/h which becomes 2/3 of a km as your final answer.

Hope that helps!

Answer 2

Given

• boy takes 10 minutes to walk from his house to the bus stop

• average working speed = 4km/h

To Find

• distance of bus stop from the house

Solution

1 hour = 60 minutes

1 km = 1000m

4 km = 4000 m

average speed = 4km/h

⇒ average speed = 4000m/60 min

60 min = 4000m

→ 1 min = 4000/60 m

→ 1 min = 400/6 m

distance from bus stop to house = 400/6 m × 10

→ distance from bus stop to house = 4000/6 m

→ distance from bus stop to house = 666.6m

Distance from bus stop to house is 666.6m
