Question

12) I travelled from Kolhapur to Nashik in 6 hours at the speed of 77 kmph. By how much should I haveincreased my speed in order to reach half an hour earlier?​

Answer 1

Answer:

7kmph must be increased to reach half an hour early

Step-by-step explanation:

Distance = speed * time

              = 77 * 6 = 462kms

now take time = 6 - half an hour = 5 1/2 = 11/2 hours

then new speed = distance / time

                           = 462 / 11/2

                           = 462*2/11 = 84

speed increased =84-77= 7
