Q:

The distance of the college and home of Rajeev is 80km. One day he was late by 1 hour than the normal time to leave for the college, so he increased his speed by 4km/h and thus he reached  to college  at the normal time. What is the changed (or increased) speed of Rajeev?

A) 28 km/h B) 30 km/h
C) 40 km/h D) 20 km/h
 
Answer & Explanation Answer: D) 20 km/h

Explanation:

Let the normal speed be x km/h, then 

80x-80(x+4)=1

x2+4x-320=0

x (x + 20) - 16 (x + 20) = 0

(x + 20 ) (x - 16) =0

 

x = 16 km/h

 Therefore (x + 4) = 20 km/h

 Therefore increased speed = 20 km/h

A) 996 B) 1000
C) 999 D) 1001
