<span>Time needed for drive a distance 100 km at 100 km/h:
t1 =100/100
= 1 h
Time needed for drive a distance 40 km at 45 km/h:
t2 =40/45
=0.8 h
t3 =3h 15m - 1 h- 0.8 h
=1.45 h
Distance to town equals:
s3 =270-100-40
=130 km
Least speed needed to arrive in time for the interview:
v3 =130 km/1.45 h
=89.65 km/h
The answer is 89.65 km/h</span>
