A Car Is Running At 7/10 Of Its Own Speed Reached A Place In 22 Hours. How Much Time Could Be Saved If The Train Would Run At Its Own Speed ?

Answer»

Since the car RUNS at 7/11 th of its own speed, the time it take is 11/7th of its usual speed.

LET the usual time taken be t HOURS

then we can WRITE, 11t / 7 = 22

or t = 22 * 7 / 11 = 14 hours

Time saved = 22 - 14 = 8hours.
