<PRE><B>Question 921335</B>
A car travels from A to B, in 45 minutes with speed of 40km/hr.
 If the speed is increased by 10km/hr what will be the time to cover the same distance.*
:
since we are dealing in km/hr, change 45 min to .75 hrs
:
Let t = time traveled at 50 km/hr
write a distance equation dist = speed * time
50t = 40 * .75
50t = 30
t = 30/50
t = .6 hr or 36 min</PRE>
