A bus moving along a straight highway from point P to point Q at a distance of 3 km (from P) then to point R at a distance of 5 km from Q and then to point S at a distance of 7 km from point R, then back to point Q and finally to the point R (all via the same path). Find the distance travelled by bus in km.

Three students, A, B, and C, start from point P at the same time on their bicycles to go to point Q. A reaches point Q first, turns back, and meets B at a distance of 5 km from Q. When B reaches Q, he also turns back and meets C at a distance of 3 km from Q. If A’s speed is three times C’s speed, what is the distance (in km) between points P and Q?

A vehicle moves from point P to Q to R to S in a circular path as shown in the below figure. Find the distance travelled by the vehicle in km

Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the eastbound car has traveled 3 kilometers. If the two cars are now a straight-line distance of 5 kilometers apart, how far has the northbound car traveled? kilometers
