Question

When covering a distance of 30 km using a bicycle, Vishal takes 2 hours more than Aman. If Vishal doubles his speed, he would take 1 hour less than Aman. What is the speed at which Vishal travels in the begining?

Answer 1

Answer:

5 km/h

Step-by-step explanation:

Lets say,

for vishal: speed= Vv

for aman: speed = Va

time = distance/ speed.

in case 1: 30/Vv = 30/Va +2

in case 2: 30/2Vv = 30/Va -1

solving them we get,

Vv= 5 km/h and Va=7.5 km/h
