Question

a car is moving at an average speed of 202/5 km/hr. How much distance will it cover in 15/2 hrs?

Answer 1

answer: 
         we know that ,
  speed =  distance/time
or distance = speed *time
 or distance = 202/5*15/2
       Distance=303 km

hope this helps you !!

Answer 2

speed = distance / time
we need distance, so by transfering time into LHS
speed × time = distance
so, distance = time × speed
                   = 15/2 hr × 202/5 km/hr  { hr and hr gets cancel}
                   = 3030 / 10 kms
                   = 303 kms
therefore, distance = 303 kms
