Question

a car covers 60km with a uniform speed of 120 kmph and the next 60 km with a uniformspeed of 80kmph the total time taken by the car is

Answer 1

Answer:

Alright so the answer i believe is 1hr 15m

Explanation:

This equation equals to Time= Distance over speed

so 60 divided by 120 is half an hour

and 60 divided by 80 is 2/3 of an hour

add a half to 2/3 and it gets you 1 and a quarter

Answer 2

Answer with Explanation:

GIVEN,

1st 60 km => 120 kmph

next 60 km => 80 kmph

Total time=?

1st 60 km,

speed =  distance/ time

=> time = distance / speed

=> time = 60 / 120

=> time = 1 / 2 hours

=> time = 30 mins

2nd 60 km,

speed = distance / time

=> time = distance / speed

=> time = 60 / 80

=> time = 3 / 4 hours

=> time = 40 mins

Therefore,

Total time = 30 + 40

                 = 70 mins

                 = 1 hour 10 mins

∴ ANSWER : 70 mins or 1 hour 10 mins
