If you walked all three trails in one day, how far would you walk? Write the answer in meters and kilometers
nordsb [41]

Answer:

a. Central Park 2.542 km, Marine Park 1.28 km, Van Cortlandt Park 2.30 km

b. 6.122 km

Further explanation

Given:

Van Cortlandt Park’s walking trail is 1.02 km longer than Marine Park’s.

Central Park’s walking trail is 0.242 km longer than Van Cortlandt’s.

Question a. Fill in the missing information in the chart below.

Central Park ____ km

Marine Park 1.28 km

Van Cortlandt Park ____ km

Problem solving:

From the information above, only Marine Park's walking trail has known at 1.28 km.

Because Van Cortlandt Park’s walking trail is 1.02 km longer than Marine Park’s, then we must add the Marine Park's with 1.02 km to get the Van Cortlandt Park's.

Van Cortlandt Park's walking trail = 1.28 km + 1.02 km

Thus, Van Cortlandt Park's walking trail is 2.30 km.

Next, we find out walking Central Park.

Because Central Park’s walking trail is 0.242 km longer than Van Cortlandt’s, then we must add the Van Cortlandt’s with 0.242 km to get the Central Park's.

Central Park's walking trail = 2.30 km + 0.242 km

Thus, Central Park's walking trail is 2.542 km.

Question b. If a tourist walked all 3 trails in a day, how many kilometers would he or she have walked?

Problem solving:

We have to add up the entire walking trail.

Central Park 2.542 km

Marine Park 1.28 km

Van Cortlandt Park 2.30 km

2.542 km + 1.28 km + 2.30 km = 6.122 km

If a tourist walked all 3 trails in a day, he or she would travel a distance of 6.122 km.
