Two cars leave from the same point (A) and travel along a straight road, which are at angle of 78° to each other. If their speed
s are 120 km/h (truck) and 90 km/h (car) respectively, how far apart will they be after one half hour?
1 answer:
T=(60cos78, 60sin78)
T=(12.47, 58.69)
C=45
d=√((45-12.47)^2+58.69^2)
d≈67.1km
