Cities A,B and C are at a distance of 72 km, 80 km and 84 km respectively from Ram's home. He observed that he can cover 5 km in 20 minutes on his cycle. If he has 5 hours time limit, which city he can reach on cycle if he travels at observed speed?
We know that the distance covered in 20 minutes is 5 km.
Assume that the distance covered in 5 hours be x.
Now, we have to find the value of x.
20x=5×60×520x=1500
x=75 km
Since city A is 72 km from Ram's home, he can reach city A in 5 hours with the given speed.
