You can put this solution on YOUR website! a car covers the given distance at a speed of 30 mph.
however if he were to halt for a fixed number of minutes per hour, its average speed reduced to 24 kph.
for how long the car halt?
:
let the distance = 30 mi, a 1 hr trip without a stop
Write a time equation; time = dist/speed
:
Let h = the halting time in hrs
h = -
h = -
h = hr, which is a 15 minutes halt each hour
