Problema Solution
In stormy conditions, a delivery truck can travel a route in 14 hour. In good weather, the same trip can be made in 10.5 hour because the truck travels 15km/hour faster. Find the speed of the truck in stormy weather and in good weather.
Answer provided by our tutors
Let Distance travelled = x
Speed on stormy conditions = x/14
Speed on good weather day = x/10.5
x/10.5-x/14 = 15
=> 3.5x = 15*14*10.5
=> x = 630 km
Hence speed on stormy day = 630/14 = 45 km/hr
Speed on good weather day = 60 km/hr
