Answer:
Step-by-step explanation:
time equals to 30 minutes
1 minut equals to 60 minut is equals to 30/60hr=1/2hr
speed is equals to 60 km/HR
distance is equals to speed into time
60*1/2=30km
and ..
distance same in 30 km
time is equals to 20 minute
=20/60hr=1/3hr
speed =distance ×time
30/(1/3)=
30×3=90km/HR.....
thank you
