Question

Find the distance covered by the particle in:

(a) between t = 30 min. and t = 40 min.​

Answer 1

Distance = speed × time

let the speed be 10km/hr

Distance of A=10×30×60=1800m

Distance of B=10×40×60=2400m

Distance between A and B= 2400-1800

600m

(multipled by 60 to convert into seconds)
