AFCAT I 22 Jan 2025 Shift 2 Paper

Let the speed of the bus be xkm∕hr
Speed of car =88km∕hr
⇒ Relative speed =(88−x)km∕hr
Total distance covered in 40 seconds =120+80=200m
According to the question
(88−x)×40×5∕18=200
Multiplying by 5∕18 to convert the units into m∕sec.
‌(88−x)×5∕18=200∕40
‌⇒88−x=5×18∕5
‌⇒88−x=18
‌⇒x=88−18
‌⇒x=70km∕hr
∴ Speed of bus is 70 km/hr
