Finn goes walking. He starts at point A and travels at a speed of 4 km/h for 1.5 hours to point B.
He then travels at a speed of 5 km/h to point C.
The scale diagram shows his route.
How many minutes does it take for Finn to walk from point B to point C?
I'd appreciate a real answer please.

Distance, rate and time problems are a standard application of linear equations. When solving these problems, use the relationship rate (speed or velocity) times time equals distance.

 \[r\cdot t=d\]

For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h)(4h) = 120 km.

The problems to be solved here will have a few more steps than described above. So to keep the information in the problem organized,  use a table.

Step-by-step explanation:

Joey and Natasha start from the same point and walk in opposite directions. Joey walks 2 km/h faster than Natasha. After 3 hours, they are 30 kilometres apart. How fast did each walk?

Who or WhatRateTimeDistance

Natashar\text{3 h}\text{3 h}(r)

Joeyr + 2\text{3 h}\text{3 h}(r + 2)

The distance travelled by both is 30 km. Therefore, the equation to be solved is:

\begin{array}{l} 3r&+&3(r&+&2)&=&30 \\ 3r&+&3r&+&6&=&30 \\ &&&-&6&&-6 \\ \midrule &&&&\dfrac{6r}{6}&=&\dfrac{24}{6} \\ \\ &&&&r&=&4 \text{ km/h} \end{array}

This means that Natasha walks at 4 km/h and Joey walks at 6 km/h.

answer: i guess 105 degrees?
