Question

​

Answer 1

hey mate❤

given here

Time T1= 30 min = 0.5 hours

speed S1=60 km/hours

so,

Distance = Time × speed

D1 = 0.5 × 60

= 30.0 km

= 30 km

Again ,

Time T2= 20 min = 1/3 Hours

Distance D2 = 30 km

Speed = S2

speed s2 = Distance / time

so,

Speed (S2)= 30×1/3

= 10 Km /Hours

Thus:--

cover the same distance in 20 min should be average speed =10 km /hours
