A boat is traveling upstream at 30 km/h with respect to the water of a river. The water is flowing at 10.0 km/h with respect to the ground. A child on the boat walks from back to front at 3.0 km/h with respect to the boat. What are the magnitude and direction of the child's velocity with respect to the ground? Select one: O a. 23 km/h upstream direction like the boat O b. 23 km/h downstream direction like the river Oc. 17 km/h downstream direction like the river O d. 17 km/h upstream direction like the boat

What is the answer for this question
ר
A boat is traveling upstream at 30 km/h with respect to the water of a
river. The water is flowing at 10.0 km/h with respect to the ground. A child
on the boat walks from back to front at 3.0 km/h with respect to the boat.
What are the magnitude and direction of the child's velocity with respect
of
to the ground?
Select one:
O a. 23 km/h upstream direction like the boat
O b. 23 km/h downstream direction like the river
O. 17 km/h downstream direction like the river
O d. 17 km/h upstream direction like the boat
