Question

Timed! I would really appreciate some help! thank you!

Andy runs for 30 minutes at a speed of 10km/h. How far did he run? (Hint: remember to convert the minutes to hours before calculating distance.) *

3km
5km
150km

Answer 1

x = 5[km]

Step-by-step explanation:

We must convert the time from minutes to hours.

`t=30[min]*(1h)/(60min)= 0.5[h]\\`

We know that speed is defined as the relationship between space and time.

`v=x/t`

where:

x = space [m]

t = time = 0.5 [h]

v = velocity [m/s]

Now replacing:

`x = 10[(km)/(h) ]*0.5[h]\\x=5[km]`
