Question

a train accelerated from 20 km/hr to 80km/hr in 4 minutes.how much distance does it cover in this period?assume that the tracks are straight? ​

Answer 1

Answer:

in this question we will have to use distance formula

(v-u)/t,here ‘v’ is the final velocity and ‘u’ as initial velocity ‘t' refers to the time indicated in question

by this formula we get

(80-20)/4=

60/4=

15km
