Question-----------------------
A car travelling with 5/7 of its actual speed covers 42 km in 1 hr 40 min 48 sec find actual speed car????
ANSWER------------------------
1 hr = 60 min
1 min = 60 secs
So start with 48 secs first which is 48/60 min = 0.8 min
Now, it is 1 hr 40.8 min.
40.8/60 = 0.68 hr
So the time covered is 1.68 hrs.
speed = distance/time
(5/7)*actual speed = 42 km / 1.68 hr
(5/7)*actual speed = 25
actual speed = 25*(7/5) = 35 km/hr....
❣️❣️Hope it helps ❣️❣️
