Answer 1

Answer:

Vavg1=(2*12*5/12+5)*10

Vavg1=70.58km/hr

t1=d/70.58=0.014d

Vavg2=d/t2

t2=d/60=0.016d

t1<t2

Ramu made total journey in less time

Answer 2

Answer:

Ramu

Step-by-step explanation:

RAMU:

journey to Trivandrum = 120km/hr

" from Trivandrum = 50km/hr

Sum = 170km/hr

SALIM:

journey to Trivandrum = 60km/hr

" from Trivandrum = 60km/hr

Sum = 120km/hr

As Ramu travelled at a higher speed, he made the total journey in less time.
