The route is long 175 km. On the first-day first regiment went at an average speed of 14 km/h and back at 24 km/h. On the second day went second regiment on the same route at an average speed of 25 km/h there and back.

Which regiment will take the route longer?

Correct answer:

x =  1

Step-by-step explanation:

s=175 km v1=14 km/h v2=24 km/h v3=25 km/h  t1=v1s+v2s=14175+24175=1682100+1681225=1682100+1225=1683325=24475=19241919.7917 h t2=v3s+v3s=25175+25175=25175+175=25350=14 h  t1 > t2 19.791666666667 h > 14 h  x=1
