Step-by-step explanation:
Total distance covered by ran = 80 km
And, total time taken in journey
t = t1 + t2
t =D1/S1 + D2/S2
where D1 = 1st dustance
D2 = 2nd Distance
S1 = speed of 1st travel
S2 = Spees of 2nd travel
t = total time
t1 = time of 1st travel
t2 = time of 2nd travel
Well
t =D1/S1 + D2/S2
= 30/60 + 50/20
Total time = 3 Hrs
Therefore, Average Speed
= total Distance ÷ total time
= 80km ÷ 3hrs
= 26.67 km/hr
Wish u best of luck
All the best
