A car can finish a certain journey in 10 hours at the speed of 48 km/hr. By how much should its speed be increased so that it may take only 8 hours to cover the same distance?

Text Solution

Distance of the entire journey `=(48xx10)`km `=480`km
If the time taken `= 8` hours, then increased speed` = (480/8)` km/hr`=60`km/hr
`therefore` Increased in speed` =60`km/hr`−48`km/hr`=12`km/hr
