Answer:
1 minute
Step-by-step explanation:
1km = 1000m
30km = 30000m
30km ÷ 60 = 500m
it takes one hour to go 30km or a ratio of 30km to 1hour. 1hour is also 60minutes. 30:60
divide both sides by 60 gets 500m and the amount of time to go that distance 1 minute
Answer:
1/60 hr or 1 minute
Step-by-step explanation:
30 km per hour
30 km : 1 hr
convert 500 metres to km
1 km = 1000 metres
500 ÷ 1000 = 0.5 km
using ratios
30 km : 1 hr
0.5 km : x hr
to get from 30 to 0.5 multiply by 1/60 ( we got this from doing 0.5 ÷ 30) , so do the same to the other side
1 hr × 1/60 = 1/60 hr
you can convert to minutes = 1/60 × 60 = 1 minute
