Given : Trump takes 120 min more than Biden to cover a distance of 54 km.

Trump covers the distance by 60 min less than Biden by doubling his​ speed

To Find : the speed of trump  

Solution:

Distance = Speed * Time

Let say  Biden  Speed  =  x km/hr

Time taken by Biden to cover 54 km  = 54/x  hrs

Speed of Trump  = y km/hr

Trump takes 120 min more than Biden to cover a distance of 54 km.

120 = 2 hrs  

=> 54/ y  = 54/x  + 2    Eq1

he covers the distance by 60 min less than Biden by doubling his​ speed

60 mins = 1 hr

speed = 2y  ( doubles )

=> 54/2y   = 54/x  -  1   Eq2

Eq1 - Eq2

=> 54/y  -  54/2y  =   3

=> 27/y  = 3

=> y  = 9   km/hr

Speed of Trumph = 9 km/hr

on doubling = 18 km/hr
