A police is chasing a culprit going n a motorbike. The motorbike crosses a turning at a speed of 72 km/h.
The jeep follows it at a speed of 90 km/h, crossing the turning tenseconds latert than the bike. Assuming that they tavel at constant speeds, how far from the turning will the jeep catch up with the bike?

Explanation

Speed of movorbike ` = 72 km h^(-1) = 20 ms^(-1)` ,
Speed of police jeep ` = 1 08 kmh^(-1) = 30 ms^(-1)`
Let the jeep catch up the bike after (t) seconds. Therefore, ` 30 t = 20 ( t= 10) or ` t= 20 ,
Distance travelled by jeep in ` 20 s`
`= 300 xx 20 = 600 m`.
