Ответ:
50 seconds
Solution;t = d /v
where t is the time taken, d is the distance and v is the speed
d= 70 m and s= 1.4 m/s
Therefore;
t = 70/1.4
= 50 seconds
b) Answer;40 meters
Solution;dc = Vc × t
Where dc is the distance down stream, Vc is the velocity downstream and t is the time taken
Vc = 0.8 m/s
t = 50 seconds
Therefore;
dc = 0.8 × 50
= 40 meters
c) Answer;55 degrees
Solution;cosA = 0.8/1.4
A = 55.15 ° with the horizontal (shore) upstream
Therefore; the angle to aim from the shore is 55°
