Question

MARKING BRAILIEST:

The average human walks at a speed of 5 km per hour. If your PE teacher asks you to walk for 30 minutes in gym class, how far would you walk (km)?

SECOND QUESTION:
The posted speed limit on the road heading from your house to school is 45 mi/h, which
is about 20 m/s. If you live 8 km (8,000 m) from school, how long will it take you to get to school if there is no traffic? Convert your answer to minutes.

Answer 1

Step-by-step explanation:

1) 60 minutes =1 hour

30 minutes =0.5hours

Average human speed = 5 km/h

Distance in 1 hour = 5km

Distance in 0.5 hours = 5×0.5=2.5km

2)Speed = 20m/s

Distance = 8000m

Speed = Distance /Time

Time = Distance/Speed

=8000/20

=400 seconds = 6 minutes 40 seconds = 6.6667minutes
