Question

7. A boat is traveling upstream at 14km/h with respect to a river that is flowing at 6km/h (with respect to the ground). A man runs directly across the boat, from one side to the other, at 6km/h (with respect to the boat). The speed of the man with respect to the ground is (A) 10 km/h (B) 14 km/h (C) 18.5 km/h (D) 21 km/h (E) 26 km/h​

Answer 1

Answer:

B 14km/h is the answer

Explanation:

all the best

Answer 2

Ans: Correct option is B) 14 km/h

Explanation: Given: Vb (upstream) = 14km/h

                                 Vr (relative) = 6km/h

                                 VR =6km/h

 (Vb-Vr) + VR=

 (14-6+6) = 14 km/h

 .. The speed of the man with respect to the ground is 14km/h
