Question

A train is travelling at the rate of 60 km per hour on a circular track. Through what
angle will it turn in 15 seconds if the radius of the track is
5
6
km.

Answer 1

Answer:

see atq speed of train =60km/h

that simply means that =60km/60min

bcs 60 min =1h

now the distance traveled by train at 15 sec =15/60

Step-by-step explanation:

60/60=1

and 15/60=1/4

now 1×1/4=1/4

distance traveled at 15 sec is 1/4 km

theta =l/r

so

1/4/5/6= 3/10

so the angle is 3/10 radians
